-Up DC_DC Converter with voltage regulator and detector NO.EA-237-160330 OUTLINE RP600K series are high efficiency, current mode step-up DC-DC converter ICs with a v oltage regulator and a voltage detector. This converter starts up of low voltage (typ. 0.8V) operation from one or two alkaline or nickel-metal-hydride (NiMH) batteries, or a single Li+ battery. This IC consists of a reference voltage unit with soft start, error amplifiers, PWM comparator, protection circuits such as a current limit circuit, an internal switch transistor, an oscillator, and PWM/VFM mode control circuit. A low ripple high efficiency step-up DC/DC converter can be composed of RP600K series with only an inductor, a diode, divider resistors and capacitors. In terms of output voltage setting, fixed type and adjustable with external divider resisters type are available. Output voltage is from 2.3V to 5.5V. The built-in LDO Regulator(VR ) consists of a reference voltage unit, an error amplifier, output voltage setting resister net, a short current limit circuit, an output transistor, and so on. To prevent the inrush current at star t-up, soft-start function is included. The Soft-start time is typically 200µs. The output voltage is fixed internally and the output range is from 1.5V to 5.0 This IC has an MODE pin. When the MODE pin is set as "H", the DC/DC converter control becomes fixed PWM control, and the LDO becomes the fast mode. When the MODE pin is set as "L", the DC/DC converter is automatic PWM/VFM control and the LDO becomes low power mode*. The voltage detector always turns on. The output is Nch open drain type. Since the package is DFN( PL)2527-10, so high density mounting on board is possible. If the internal chip temperature is beyond the certain level, system reset will work, or thermal shutdown circuit is included in the IC. *) The switch-over point is fixed internally. As for A/D version, regardless the MODE pin signal, LDO mode is always set at fast mode. As for B/C version, regardless the MODE pin signal, when the DC/DC converter is active, LDO becomes fast mode. Functions A version: The input power supply of the built-in voltage regulator (LDO) is the output of the built-in DC/DC converter. After the soft-start function of the DC/DC converter, the LDO starts up. The built-in voltage detector outputs "L" when the supervised level becomes lower than the set detector threshold level. The output delay circuit for release the voltage detector is also built-in and the delay time is set at typically 10ms. B version: The input power supply of the built-in voltage regulator (LDO) and the DC/DC converter is VDD pin. Each channel is individual. The minimum operat ing voltage of the LDO is 2.0V. The output of the DC/DC converter is fixed internally. If the DC/DC is active, the LDO mode becomes fixed fast mode. The built-in voltage detector outputs "L" when the supe rvised level becomes lower than the set detector threshold level. The output delay circuit for release the voltage detector is also built-in and the delay time is set at typically 10ms. C version: The input power supply of the built-in voltage regulator (LDO) is the output of the built-in DC/DC converter. The voltage regulator is always active. The output of the DC/DC converter is fixed internally. The built-in voltage detector outputs "L" when the supervised level becomes lower than the set detector threshold level. The output delay circuit for release the voltage detector is not included. The hysteresis range can be selected from 30% of the set voltage detector threshold to 80% of the detector threshold. D version: The input power supply of the built-in voltage regulator (LDO) and the DC/DC converter is VDD pin. The output of the DC/DC converter is adjustable wi th external divider resisters. The built-in voltage detector outputs "L" when the supervised level becomes lower than the set detector threshold level. The output delay circuit for release the voltage detector is also built-in and the delay time is set at typically 10ms.

During on time of the transistor, when the voltage added on to the inductor is described as VIN, the current is VINt/L. Therefore, the electric power, PON, which is supplied with input side, can be described as in next formula. dt t/L V P ton IN With the step-up circuit, electric power is supplied from power source also during off time. In this case, input current is described as(VOUTVIN)t/L, therefore electric power, POFF is described as in next formula. dt )t/L V (V VP INOUT tf In this formula, tf means the time of which the energy saved in the inductance is being emitted. Thus average electric power, PAV is described as in the next formula. dt} )t/L V (V V dt t/L V { toff)1/(ton P INOUT tf IN ton
In PWM control, when tf=toff is true, the inductor current becomes continuous, then the operation of switching regulator becomes continuous mode. In t he continuous mode, the dev iation of the current is equal between on time and off time. Further, the electric power, PAV is equal to output electric power, VOUT IOUT , thus, When IOUT becomes more than V INtontoff/(2L(ton＋toff)),the current flows through the inductor, then the mode becomes continuous. The continuous current through the inductor is described as lconst, then, In this moment, the peak current, Ilxmax flowing through the inductor and the driver Tr. is described as follows: With the formula 4 , 6 and Ilxmax is However, ton=(1-VIN/VOUT)/fosc Therefore, peak current is more than I OUT. Considering the value of ILxmax, the condition of input and output, and external components should be selected. In the formula 7, peak current ILxmax at discontinuous mode can be calculated. Put lconst ＝0 in the formula. The explanation above is based on the ideal calculation, and the loss caused by Lx switch and external components is not included. Please select the inductor and the diode with current peak to the standard(Formula 8). EXTERNAL COMPONENTS and TECHNICAL NOTES *Make enforce both V IN and GND lines sufficient. Large current by switching may flow through the V IN line and GND line. If their impedance is high, the internal voltage of the IC may shift by the switching current and the operation may unstable. When the built-in Lx switch tu rns off, a spike noise may be generated caused by the inductor, therefore recommendation range of the voltage rating of capacitor C3 and the shottky barrier diode is 1.5 or more times as much as the set output voltage. *Select a diode with low Vf (Shottky barrier diode), low reverse current, fast switching speed. *In this IC, after the step-up, V OUT1 voltage is used as a main power source of the IC. That means the capacitor C3 between VOUT1 and GND has a role of the bypass capacitor of t he IC. Therefore, to select the capacitor C3 between V OUT1 and GND, consider the bias charac teristics, and mean value must be 10 F or more. Set the capacitor as close as possible to the VOUT1 pin and GND pin. A capacitor C1 between VIN and GND, select 10F or more capacitance ceramic type. *As for the capacitor C2 between V OUT2 and GND, consider the bias characteristics, put the 2.2 F or more ceramic capacitor as close as possible to the VOUT2 pin and GND pin. -In case of A, C, and D version, V OUT2 operates with VOUT1 voltage as power supply. Therefore, the capacitor C3 between VOUT1 and GND has a role of the bypass capacitor of the V OUT2. If the position of C2, C3 and GND are not close one another, put a 0.001uF capacitor between VOUT1 and the GND of C2.
*Select the inductance value according to the set output voltage. If V OUT13.6V is true, 4.7 H is the recommendation value, and if V OUT1<3.6V is true, 3.3 H is the recommendation value. Low DCR, enough permissible current, and uneasy to become magnetic saturati on characteristics are preferable. If the inductance value is too small, the current of Lx transistor and i nductor current or Lx peak current at maximum load may exceed the absolute maximum rating. Choose an appropriate value. *If the spike noise of the Lx pin is large, put the snub circuit (serial CR connection) in parallel with the diode D1 and reduce the spike noise. The time constant of CR depends on the actual PCB, and efficiency may be effected, therefore fully evaluation on the actual PCB is necessary. (As much as 10 and 300pF is the nominal value.) *The performance with this IC largely depends on the per ipheral circuits. Do not exceed the ratings of voltage, current, and power for each external component and IC and consider the PCB layout. DC/DC output voltage setting method (for D version) DC/DC output voltage(VOUT1) is determined by the divider resisters, R2 and R3. VOUT1=VFBx(R2+R3)/R3 (VFB=0.6V) The recommendation range of R2+R3 is equal or less than 100k. GENERAL TECHNICAL NOTES (Common for all versions:) *If the built-in detector is not used, set the VDOUT pin and VSENSE pin to the GND. *If the output of the DC/DC (VOUT1) is under the condition of the output short (VOUT1 < 0.5V), to protect the IC itself, the switching will stop. However, an external path remains between Vin and GND and large current flows. *When the LDO start-up, inrush current suppression function operates and until the output voltage reaches to the set output voltage, the maximum current is limited around t he short current limit. Start-up load current must be low. (A, C, and D version) The output of the DC/DC(V OUT1) is input voltage for LDO (VOUT2), therefore VOUT1-VOUT2 is dropout voltage for LDO, therefore, the decide the voltage of VOUT1 with considering the load current of VOUT2 and output characteristics of VOUT1 and VOUT2. If the DC/DC converter must limit the current, to protect the IC, LDO turns off. When the DC/DC starts up, if a heavy load is forced, or the capacitor, C3 between VOUT1 and GND is large, current limit may operate and start-up of the LDO may be slow. Especially, the step-up ratio is high, this phenomenon is likely to happen, and fully evaluation is necessary. When the LDO starts-up, inrush current limit operates, and DC/DC converter can avoid the heavy load, however, if the DC/DC converter's load current is large, LDO may turn off.

(1) DC/DC Converter (Start-up) When the CE signal changes from "L" to "H", the DC/DC converter starts up. The DC/DC converter of the RP600 can start up with the low input voltage such as 0.8V. To realize this, the RP600 has a low-boost mode. Until the output voltage 1 reaches 1.94V (Typ.), the operation mode is low-boost mode. When the output voltage becomes equal or more than 1.94 V, then to suppress the inrush current, soft-start operation starts until the output voltage 1 becomes set output voltage. *At the low-boost mode, the oscillator frequency becomes low, 200kHz (Typ.) Therefore, compared with the normal operation mode at 1.2MHz, the boost ability will worse. Soft-start time depends on the set output voltage, the input voltage, the ambient temperature, and the load current. (Over-current protection operation) If the Lx peak current may reach 1.4A (typ.), Lx peak current limit circuit may operate and control the duty ratio. If the output voltage becomes down to typically 0.5V or less, the switching stops to protect the IC. However, large current flows between Vin and GND via an external component. (2) LDO Typically 1.6ms from starting the soft-start operation of the DC/DC converter, LDO starts up its operation. When the LDO starts up, to suppress the inrush current, LDO operation will start with soft-start and typically 0.2ms, reaches the set output voltage. Until the output voltage reaches to set output voltage, the maximum current limits around the short current limit. Depending on the load condition and the capacity of the capacitor, C2, the start-up time will be long. (Over current protection operation) The LDO has an over-current limit circuit, and if the DCDC converter limits the over current typically 0.2ms or longer than 0.2ms, then LDO will be into standby mode. After that, when the DC/DC conver ter becomes VFM mode, or normal PWM mode again, then restart with soft-start operation.

(1) DC/DC Converter and VD (Start-up) The V SENSE pin is connected to the DC/DC output (V OUT1), and the VD output (V DOUT) is connected to the CE pin.
