600mA Synchronous Step-Down DC/DC Converter + Dual LDO Regulator ˙GENERAL DESCRIPTIONç The XCM520 series is a multi chip module which comprises of a 600mA driver transistor built-in synchronous step–down DC/DC converter and a dual CMOS LDO regulator. The device is housed in small USP-12B01 package which is ideally suited for space conscious applications. The XCM520 can replace this dual DC/DC to eliminate one inductor and reduce output noise. The DC/DC converter with a built-in 0.42ЊP-channel MOS and a 0.52ЊN-channel MOS provides a high efficiency, stable power supply up to 600mA to using only a coil and two ceramic capacitors connected externally. The highly accurate, low noise, dual CMOS LDO regulator incl udes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensation circuits inte rnally. The series is also fully compatible with low ESR ceramic capacitors. This high level of output stability is maintained even during fr equent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of fr equencies. The EN function allows the output of each regulator to be turned off independently, resulting in greatly reduced power consumption. ˙APPLICATIONSç ˔Mobile phones, Smart phones ˔Bluetooth headsets ˔WLAN PC cards ˔Portable HDDs, SSDs ˔PDAs, PNDs, UMPCs ˔MP3 players, Media players ˔Portable game consoles ˔Cordless phones, Radio communication equipment ˙FEATURES <DC/DC Convertor Block> Driver Transistor : 0.42Ω P-channel MOS Built-in Switching Transistor : 0.52Ω N-channel MOS Built-in Input Voltage Range : 2.7V ʙ 6.0V Output Voltage Range : 0.8V ʙ 4.0V High Efficiency : 92% (TYP.) * Output Current : 600mA Oscillation Frequency : 1.2MHz,3.0MHz (±15%) Soft-Start : Built-In Soft-Start Current Limiter Circuit : Constant Current & Latching Control : Fixed PWM, Auto PWM/PFM *Performance depends on external components and wiring on PCB wiring. <Dual LDO Regulator Block> Maximum Output Current : 150mA (Limiter 300mA TYP.)

ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ˔DC/DC BLOCKç The DC/DC block of the XCM520 series cons ists of a reference voltage source, ramp wave circuit, error amplifier, PWM comparator, phase compensation circuit, output voltage adjustment resistor s, P-channel MOSFET driv er transistor, N-channel MOSFET switching transistor for the synchronous switch, curr ent limiter circuit, UVLO circ uit and others. (See the block diagram above.)ç By using the error amplifier, the voltage of the internal voltage reference source is compared with the feedback voltage from the VOUT3 pin through split resistors, R1 and R2. Phase compensation is performed on the resulting error amplifier output, to input a signal to the PWM comparator to determine the turn-on time during PWM operation. The PWM co mparator compares, in terms of voltage level, the signal from the erro r amplifier with the ramp wave from the ra mp wave circuit, and delivers the resulting output to the buffer driver circuit to cause the Lx pin to output a switching duty cycle. This process is continuously performed to ensure stable output voltage. The current feedback circuit monitors the P- channel MOS driver transistor current for each switching operation, and modulates the error amplifier output signal to pr ovide multiple feedback signals. This enables a stable feedback loop even when a low ESR capacitor such as a ceramic capacitor is used ensuring stable output voltage. ç <Reference Voltage Source> The reference voltage source provides the reference voltage to ensure stable output voltage of the DC/DC converter.ç ç <Ramp Wave Circuit> The ramp wave circuit determines switching frequency. The frequenc y is fixed internally and can be selected from 1.2MHz or 3.0MHz. Clock pulses generated in this circuit are used to produce ramp waveforms needed for PWM operation, and to synchronize all the internal circuits. ç <Error Amplifier> The error amplifier is designed to monitor output voltage. T he amplifier compares the reference voltage with the feedback voltage divided by the internal split resistors, R1 and R2. When a voltage is lower than the reference voltage is fed back, the output voltage of the error amplifier increases. The gain and frequency characteristi cs of the error amplifier output are fixed internally to deliver an optimized signal to the mixer. ˙TYPICAL APPLICATION CIRCUIT VIN CL1 CIN1 CIN2 CL3 L 103 6 Lx VIN2 EN2 VOUT2 VOUT3 EN1 VSS VOUT1 VIN1 CL2 PGND AGND EN3/MODE ˔çDC/DC BLOCKç fOSC=3.0MHz CIN1 : 1 ЖF ( C e r a m i c ) CL1 : 1 ЖF ( C e r a m i c ) CL2 : 1 ЖF ( C e r a m i c ) L : 1.5 ЖH (NR3015 TAIIYO YUDEN) CIN2 : 4 . 7 ЖF (Ceramic) CL2 : 1 0 ЖF (Ceramic) ˔çDC/DC BLOCKç fOSC=1.2MHz CIN1 : 1 ЖF ( C e r a m i c ) CL1 : 1 ЖF ( C e r a m i c ) CL2 : 1 ЖF ( C e r a m i c ) L : 4.7 ЖH (NR4018 TAIIYO YUDEN) CIN2 : 4 . 7 ЖF (Ceramic) CL2 : 1 0 ЖF (Ceramic) ˙OPERATIONAL EXPLANATION

ç ç ç <Current Limit> The current limiter circuit of the XCM520 series monitors the current flowing through the P-channel MOS driver transistor connected to the Lx pin, and features a combination of the current limit mode and the operation suspension mode. ç ᶃçWhen the driver current is greater than a specific level, the current limit function operates to turn off the pulses from the Lx pin at any given timing. ᶄçWhen the P-channel MOS driver transistor is turned off, the limiter circuit is then released from the current limit detection state. ᶅçAt the next pulse, the P-channel MOS driver transistor is turned on. However, the P-chan nel MOS driver transistor is immediately turned off in the case of an over current state. ᶆçWhen the over current state is eliminated, the IC resumes its normal operation. The IC waits for the over current state to end by repeating the steps ᶃçthrough ᶅ. If an over current state continues for a few milliseconds and the above three steps are repeatedly perf ormed, the IC performs the function of latching the OFF state of the P-channel MOS driver transistor, and goes into operation suspension mode. Once th e IC is in suspension mode, operations can be resumed by either turning the IC off via the EN3 pin, or by restoring power to the V IN2 pin. The sus pension mode does not mean a complete shutdown, but a state in which pulse output is suspended; theref ore, the internal circuitry remains in operation. The current limit of the XCM520 series can be set at 1050mA at typical. Besides, care must be taken when laying out the PC Board, in order to prevent mi ss-operation of the current limit mode. Depending on the stat e of the PC Board, latch time may become longer and latch operation may not work. In order to avoid the effect of noise, the board should be laid out so that input capacitors are placed as close to the IC as possible.ç <Short-Circuit Protection> The short-circuit protection circuit monitors the internal R1 and R2 divider voltage from the VOUT3 pin. In case where output is accidentally shorted to the ground and when the FB point voltage decreases less t han half of the reference voltage (Vref) and a current more than the I LIM flows to the driver transistor, the short-circ uit protection quickly operates to turn off and to latch the driver transistor. In latch st ate, the operation can be resumed by either turning the IC off and on via the EN3 pin, or by restoring power supply to the VIN2 pin. When sharp load transient happens, a voltage drop at the VOUT3 pin is propagated to FB point through CFB, as a result, short circuit protection may operate in the voltage higher than 1/2 VOUT3 voltage. ç ç <UVLO Circuit> When the V IN2 pin voltage becomes 1.4V or lower, the P-channel MOS driver transistor is forced OFF to prevent false pulse output caused by unstable operation of the internal circuitry. When the V IN2 pin voltage becomes 1.8V or higher, switching operation takes place. By releasing the UV LO function, the IC performs the soft start function to initiate output startup operation. The soft start function operates even when the VIN pin voltage falls momentarily below the UVLO operating voltage. The UVLO circuit does not cause a complete shutdown of the IC, but caus es pulse output to be suspended; t herefore, the internal circuitry remains in operation. ç ç ç ç ç ç ˙OPERATIONAL EXPLANATION (Continued) VIN1 VEN3 Lx VOUT3 ILx Current Limit LEVEL Limit<数ms Restart VSS 0mA Limit>数msLimitʼa few milliseconds Limit < a few milliseconds

ç ç ç <PFM Switch Current> In the PFM control operation, until coil current reaches to a specified level (I PFM), the IC keeps the P- channel MOSFET on. In this case, on-time (tON) that the P-channel MOSFET is kept on can be given by the following formula. tON= LʷIPFM (VIN2ʵVOUT3) ˠIPFMᶃ ç <PFM Duty Limit> In the PFM control operation, the PFM duty limit (D LIMT_PFM) is set to 200% (TYP.). Therefore, under the condition that the duty increases (e.g. the condition that the step- down ratio is small), it’s possible for P-channel MOS driver transistor to be turne d off even when coil current doesn’t reach to IPFM. çˠ IPFMᶄ ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç ç < CL High Speed Discharge > XCM520AE/ XCM5AF/XCM520AG/XCM520AH series can quickly discharge the electric charge at the output capacitor (CL) when a low signal to the CE pin which enables a whole IC circuit put into OFF state, is inputted via the N-channel transistor located between the LX pin and the VSS pin. When the IC is disabled, electric charge at the output capacitor (CL) is quickly discharged so that it may avoid application malfunction. Discharge time of the output capacitor (CL) is set by the CL auto-discharge resistance (R) and the output capacitor (CL). By setting time constant of a CL auto-discharge resistance value [R] and an output capacitor value (CL) as Н(Н=C x R), discharge time of the output voltage after discharge via the N-channel transistor is calculated by the following formula.

The P-channel MOSFETs, which are connected to the V OUT pin, are then driven by the su bsequent output signal. The output voltages at the V OUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of out put current. Further, the IC's internal circuitry can be shutdown via the EN pin's signal. < Low ESR Capacitors > With the XCM520 series, a stable output voltage is achiev able even if used with low ESR capacitors as a phase compensation circuit is built-in. In order to ensure the effe ctiveness of the phase compensat ion, we suggest that output capacitor (CL) is connected as close as possible to the output pins (V OUT) and the V SS pin. Please use an output capacitor with a capacitance value of at least 1ЖF. Also, please connect an input capacitor (CIN1) of 1ЖF between the VIN1 pin and the VSS pin in order to ensure a stable power input. < Current Limiter, Short-Circuit Protection > The XCM520 series includes a combination of a fixed current limiter circuit and a fold-back circuit which aid the operations of the current limiter and circuit protection. When the load current reaches the current lim it level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the fold-back circuit start to operate, output voltage drops further and output current decreases. When the output pin is shorted, a current of about 30mA flows. < EN Pins > The IC's internal circuitry can be shutdown via the signal from the EN pin with the XCM520 series. In shutdown state, output at the V OUT pin will be pulled down to the V SS level via R1 and R2. The operational logic of the IC's EN pin is selectable (please refer to the selection guide). Note that as the standard type's regulator 1 and 2 are both ' High Active/No Pull Down', operations will become unstable with the EN pin open. Althou gh the EN pin is equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the EN pin input current will increase when the IC is in operation. We suggest that you use this IC with either a V IN1 voltage or a VSS voltage input at the EN pin. If this IC is used with the correct specifications for the EN pin, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry.

<DC/DC BLOCK> 1. The XCM520 series is designed for use with ceramic output capacitors. If, howeve r, the potential difference is too large between the input voltage and the output voltage, a ceramic capacitor may fail to absorb the resulting high switching energy and oscillation could occur on the output. If the input-output potent ial difference is large, connect an electrolytic capacitor in parallel to compensate for insufficient capacitance. 2. Spike noise and ripple voltage arise in a switching regulato r as with a DC/DC converter. These are greatly influenced by external component selection, such as the coil inductance, capacitance values, and board layout of external components. Once the design has been completed, verification with actual components should be done. 3. As a result of input-output voltage and load conditions, oscillation frequency goes to 1/2, 1/3, and continues, then a rippl e may increase. 4. When input-output voltage differential is large and light load conditions, a small duty cycle comes out. After that, 0%duty cycle may continue in several periods. 5. When input-output voltage differentia l is small and heavy load conditions, a large duty cycle comes out and may continues100% duty cycle in several periods. 6. With the IC, the peak current of the coil is controlled by the current limit circuit. Since the peak current increases whe n dropout voltage or load current is high, current limit starts operation, and this can lead to instability. When peak current becomes high, please adjust the coil inductance value and fully check the circuit operation. In addition, please calculate the peak current according to the following formula: Ipk = (VIN2-VOUT3)× OnDuty /(2×L×fOSC) + IOUT L: Coil Inductance Value fOSC: Oscillation Frequency 7. When the peak current which exceeds lim it current flows within the specified time, the built-in P-channel MOS driver transistor turns off. During the time until it detects limit current and before the built-in P-channel MOS driver transistor can be turned off, the current for limit current fl ows; therefore, care must be taken when selecting the rating for the external components such as a coil. 8.ç Depending on the state of the PC Board, latch time may become longer and latch operation may not work. In order to avoid the effect of noise, the board should be laid out so that input capacitors are placed as close to the IC as possible. ç 9.ç Use of the IC at voltages below the recommended voltage range may lead to instability. ç 10. This IC should be used within the stated absolute maxi mum ratings in order to prevent damage to the device. 11. When the IC is used in high temperatur e, output voltage may increase up to inpu t voltage level at no load because of the leak current of the P-channel MOS driver transistor. ç 12.çThe current limit is set to 1350mA (MAX.) at typical. However, the current of 1350mA or more may flow. ç In case that the current limit functions while the VOUT3 pin is shorted to the GND pin, when P-channel MOS driver transistor is ON, the potential difference for input voltage will occur at both ends of a coil. For this, the time rate of coil current beco mes large. By contrast, when N-channel MOS driver transistor is ON, there is almost no potential difference at both ends of the coil since the V OUT3 pin is shorted to the GND pin. Consequently, th e time rate of coil current becomes quite small. According to the repetition of this operation, and the delay ti me of the circuit, coil current will be converged on a certain current value, exceeding the amount of current, which is supposed to be limited originally. Even in this case, however, after the over current state continues for several ms, the circuit will be latched. A coil should be used within the stated absolute maximum rating in order to prevent damage to the device. ç ç ᶃCurrent flows into P-channel MOS driver transistor to reach the current limit (ILIM).ç ᶄThe current of ILIM or more flows since the delay time of the circuit occu rs during from the detectio n of the current limit to OFF of P-channel MOS driver transistor.ç ᶅBecause of no potential difference at both ends of the coil, the time rate of coil current becomes quite small.ç ᶆLx oscillates very narrow pulses by the current limit for several ms. ᶇThe circuit is latched, stopping its operation. ç ˙NOTES ON USE # ms

13.ç In order to stabilize VIN2 voltage level and oscillation frequency, we recommend that a by-pass capacitor (CIN) be connected as close as possible to the VIN2 and VSS pins.ç 14.ç High step-down ratio and very light load may lead an intermittent oscillation.ç 15.ç During PWM / PFM automatic switching mode, operating may become unstable at transition to continuous mode.

˔Note on use of pattern layoutsç 1. Please use this IC within the stated absolute maximum rati ngs. The IC is liable to malfunction should the ratings be exceeded. 2. The capacitor (C IN) should be connected as close as possible to the VIN and VSS pins. When wiring impedance is high, noise propagation by output current or phase discrepancy occur which results in unstable operating. In this case, please reinforce V IN and VSS rails. If the operation is still unstable, please increase input capacitance CIN. 3.
