600mA Step-down DC/DC Converter with Synchronous Rectifier NO.EA-155-230419 RP500L(DFN1616-6) is the discontinued product as of April,2023, RP500Z (WLCSP-6-P2) is the discontinued product as of February 2021. OUTLINE The RP500x Series are CMOS-based 600mA step-down DC/DC Converters with synchronous rectifier. Each of these ICs consists of an oscillator, a switching control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, protection circuits, UVLO circuit, switching transistors, and so on. A low ripple, high efficiency step-down DC/DC converter can be easily composed of this IC with only an inductor and capacitors. In terms of the output voltage, since the feedback resistances are built-in, the voltage is fixed internally. 0.1V step output can be set by laser-trim and 1.5% or 24mV tolerance depending on the output voltage is guaranteed. Mode alternative circuit works automatically for improving the efficiency. Considering fixed noise frequency, PWM fixed control type is also available. As protection circuits, the current limit circuit which limits peak current of Lx at each clock cycle, and the latch type protection circuit which works if the term of the ov er-current condition keeps on a certain time exist. The latch-type protection circuit works to latch an internal driver with keeping it disable. To release the condition of the protection, after disabling this IC with a chip enable circ uit, enable it again, or restart this IC with power-on or make the supply voltage at UVLO detector threshold level or lower than UVLO. Since packages are WLCSP-6-P2, DFN1616-6, DFN(PL)1820-6, SOT-23-6W, high density mounting on boards is possible. )This is an approximate value, because output current depends on conditions and external parts.

TYPICAL APPLICATION VIN CE LX VOUT PGNDAGND VIN CIN 10F COUT 10F VOUT 4.7H RP500x Series Symbol Parts Recommendation CIN 10F Ceramic C2012JB0J106K (TDK) COUT 10F Ceramic C2012JB0J106K (TDK) L 4.7H VLF3010AT-4R7MR30 TECHNICAL NOTES When using these ICs, consider the following points: Set the same level as AGND and PGND. Set external components such as an inductor, C IN, COUT as close as possible to the IC, in particular, minimize the wiring to VIN pin and PGND pin. Reinforce the VIN, PGND, and VOUT lines sufficiently. Large switching current may flow in these lines. If the impedance of VIN and PGND lines is too large, the internal voltage level in this IC may shift caused by the switching current, and t he operation might be unstable. The wiring between V OUT and load and between L and VOUT should be separated. Use an external capacitor CIN between VIN and GND, and COUT with a capacity of 10µF or more ceramic type. Choose an inductor with inductance range from 4.7 H to 10H. The phase compensation has been made by these values with output capacitors. The recommendation characteristics of the inductor are low DC resistance, large enough permissible current, and strong against the magnetic saturation. Inductance value may shift depending on an inductor. If the inductance value at an actual load current is low, Lx peak current may increase and may overlap the Lx current limit. As a result, over current protection may work. Over current protection circuit may be affected by self-heating and heat radiation environment. The performance of power source circuits using these ICs extremely depends upon the peripheral circuits. Pay attention in the selection of the peripheral circuits. In particular, design the peripheral circuits in a way that the values such as voltage, current, and power of each component, PCB patterns and the IC do not exceed their respected rated values. (such as the voltage, current, and power)

Operation of step-down DC/DC converter and Output Current The DC/DC converter charges energy in the inductor when LX transistor is ON, and discharges the energy from the inductor when LX transistor is OFF and controls with less energy loss, so that a lower output voltage than the input voltage is obtained. The operation will be explained with reference to the following diagrams: <Basic Circuit> <Current through L> Pch Tr L Nch Tr VIN VOUT CL GND T=1/fosc ton toff topen ILmin ILmax IL i1 i2 Step 1 : Pch Tr. turns on and current IL (i1) flows, and energy is charged into CL. At this moment, IL increases from ILmin (0) to reach ILmax in proportion to the on-time period (ton) of Pch Tr. Step 2 : When Pch Tr. turns off, Synchronous rectifier Nch Tr. turns on in order that L maintains IL at ILmax, and current IL (i2) flows. Step 3: IL (i2) decreases gradually and reaches ILILmin0 after a time period of t open, and Nch Tr. turns off. Provided that in the continuous mode, next cycle starts before IL becomes to 0 because toff time is not enough. In this case, IL value increases from this ILmin (>0). In the case of PWM control system, the output voltage is maintained by controlling the on-time period (ton), with the oscillator frequency (fosc) being maintained constant. The maximum value (IL max) and the minimum value (IL min) of the current flowing through the inductor are the same as those when Pch Tr. turns on and off. The difference between ILmax and ILmin, which is represented by I: wherein, T 1 / fosc ton toff duty (%) ton / T 100 ton fosc 100 topen toff In Equation 1, VOUT topen / L and (VIN VOUT) ton / L respectively show the change of the current at "ON", and the change of the current at "OFF".

Discontinuous mode and Continuous mode When the output current (IOUT) is relatively small, topen < toff as illustrated in the following diagram. In this case, the energy is charged in the inductor during the time period of ton and is discharged in its entirely during the time period of t off, therefore IL min becomes to zero (IL min0). When I OUT is gradually increased, eventually, t open becomes to t off (topentoff), and when I OUT is further increased, IL min becomes larger than zero (IL min>0). The former mode is referred to as the discontinuous mode and the latter mode is referred to as continuous mode. Discontinuous mode Continuous mode ILmax ILmin ton toff T=1/fosc topen IL t ILmax ILmin ton toff T=1/fosc IL Iconst t In the continuous mode, when Equation 1 is solved for ton and assumed that the solution is tonc, When ton<tonc, the mode is the discontinuous mode, and when tontonc, the mode is the continuous mode. Output Current and selection of External components The relation between the output current and external components is as follows: When Pch Tr. of LX is ON: (Wherein, Ripple Current p-p value is described as IRP, ON resistance of Pch Tr. and Nch Tr. of LX are respectively described as RONP and RONN, and the DC resistor of the inductor is described as RL.) When Pch Tr. of LX is "OFF" (Nch Tr. is "ON"): Put Equation 4 to Equation 3 and solve for ON duty of Pch transistor, D ON ton / (toff ton),

Ripple Current is as follows: wherein, peak current that flows through L, and L X Tr. is as follows: Consider ILx max, condition of input and output and select external components. The above explanation is directed to the calculation in an ideal case in continuous mode.

TIMING CHART (1) Soft Start Time In the case of starting this IC with CE In the case of starting this IC with CE, the operation can be as in the timing chart below. When the voltage of CE pin (VCE) is beyond the threshold level, the operation of the IC starts. The threshold voltage of CE pin is in between CE "H" input voltage (VCEH) and CE "L" input voltage (VCEL) described in the electrical characteristics table. Soft-start circuit operates, and after the certain time, the reference voltage inside the IC (V REF) is rising gradually up to the constant value. VCEH Soft-start Time IC Internal Voltage Reference VCEL Threshold Level Lx Voltage (VCE) (VREF) Soft-start Circuit operating (VLX) Depending on Power supply, Load Current, External Components (VOUT) Output Voltage CE Pin Input Voltage PWM mode operating during the Soft-start Time Soft-start time is the time interval from soft start circuit starting point to the reference voltage level reaching point up to this constant level. Soft start time is not always equal to the turn-on speed of DC/DC converter. The power supply capacity for this IC, load current, i nductance and capacitance values affect the turn-on speed. In the case of starting with power supply In the case of starting with power supply, when the input voltage (VIN) is larger than UVLO released voltage (VUVLO2), soft start circuit operates, and after that, the same explanation above is applied to the operation. Soft-start time is the time interval from soft start circuit starting point to the reference voltage level reaching point up to this constant level.

(2) Under Voltage Lockout (UVLO) Circuit The step-down DC/DC converter stops and ON duty becomes 100%, if input voltage (V IN) becomes less than the set output voltage (Set VOUT), the output voltage (VOUT) gradually drops according to the input voltage (VIN). If the input voltage drops more and becomes less than UVLO detector threshold (V UVLO1), the under voltage lockout circuit (UVLO) operates, the IC internal reference voltage (VREF) stops, switching transistors turn off and the output voltage drops according to the load and output capacitor COUT value. To restart the normal operation, the input voltage (VIN) must be more than the UVLO released voltage (VUVLO2). The timing chart below describes the operation with varying the input voltage (VIN).

(3) Over Current Protection Circuit, Latch Type Protection Circuit Over current protection circuit supervises the coil peak current (the current flowi ng Pch transistor) at each switching cycle, and if the current beyond the Lx current limit (ILXlim), Pch transistor is turned off. the Lx current limit of RP500x is Typ.900mA. Further, if the over current status continues equal or longer than protection delay time, or, when the Lx limit current is exceeded even once when the driver operates by duty 100%, a built-in driver is latched in the OFF state and the operation of DC/DC converter stops. Lx current limit and protection delay time is affected by self-heating and ambient environment. If the output is short and the input voltage (V IN) is drastically dropped or becomes unstable, the protection operation and delay time may vary. Protection Delay Time (tprot) Lx Current Limit (ILXlim) Lx Current Pch Tr. Current Lx Voltage (VLX) To release the condition of latch type protection, restart this IC by inputting "L" signal to CE pin, or restart this IC with power-on or make the supply voltage lower than UVLO detector threshold (VUVLO1) level. The timing chart shown below describes the changing process of input voltage ri sing, stable operating, operating with large current, reset with CE pin, stable operating, input voltage falling, input voltage recovering, and stable operating. If too large current flows through the ci rcuit because of short or other reas ons, after the delay time of latch type protection a built-in driver is latched in the OFF state and V LX signal will be "L", then output will turn off. At the point (1), release the latch type protection is realized with CE reset as changed CE signal from "L" to "H". At the point (2), release the latch type protection is realized with UVLO reset as make the supply voltage lower than UVLO detector threshold (VUVLO1) level.
