RP509x Series
0.5A/1A PWM/VFM Step-down DC/DC Converter with Synchronous Rectifier
No. EA-362-220819
OUTLINE
The RP509x is a low supply current PWM/VFM step-down DC/DC converter with synchronous rectifier
featuring 0.5 A/1 A output current(1). Internally, a single converter consists of a reference voltage unit, an error
amplifier, a switching control circuit, a mode control circuit, a soft-start circuit, an undervoltage lockout (UVLO)
circuit, a thermal shutdown circuit, and switching transistors. The RP509x is employing synchronous
rectification for improving the efficiency of rectification by replacing diodes with built-in switching transistors.
Using synchronous rectification not only increases circuit performance but also allows a design to reduce parts
count. Output voltage controlling method is selectable between a PWM/VFM auto-switching control type and
a forced PWM control type, which further reduces noise than a normal PWM control under a light load, and
these types can be set by the MODE pin. Output voltage type is selectable between an internally fixed output
voltage type and an externally adjustable output voltage type. Protection circuits in the RP509x is current limit
circuit and thermal shutdown circuit. LX current limit value (Typ.) is selectable between 1.6 A and 1.0 A.
The RP509Z is available in WLCSP-6-P6 which achieves high-density mounting on boards. Using capacitor
of 0402-/1005-size (inch/mm) and inductor of 0603-/1608-size (inch/mm) as external parts help to save space
for devices. The RP509N is available in SOT-23-6.

OPERATING DESCRIPTIONS
Soft-start Time
Starting-up with CE Pin
The IC starts to operate when the CE pin voltage (VCE) exceeds the threshold voltage. The threshold voltage
is preset between CE “H” input voltage (VCEH) and CE “Low” input voltage (VCEL).
After the start-of the start-up of the IC, soft-start circuit starts to operate. Then, after a certain period of time,
the reference voltage (VREF) in the IC gradually increases up to the specified value.
Notes: Soft start time (tSTART)(1) is not always equal to the turn-on speed of the step-down DC/DC converter.
Please note that the turn-on speed could be affected by the power supply capacity, the output current, the
inductance value and the COUT value.

Undervoltage Lockout (UVLO) Circuit
If VIN becomes lower than VSET, the step-down DC/DC converter stops the switching operation and ON duty
becomes 100%, and then VOUT gradually drops according to VIN.
If the VIN drops more and becomes lower than the UVLO detector threshold (VUVLO1), the UVLO circuit starts
to operate, VREF stops, and Pch. and Nch. built-in switch transistors turn “OFF”. As a result, VOUT drops
according to the COUT capacitance value and the load.
To restart the operation, VIN needs to be higher than VUVLO2. The timing chart below shows the voltage shifts
of VREF, VLX and VOUT when VIN value is varied.
Notes: Falling edge (operating) and rising edge (releasing) waveforms of VOUT could be affected by the initial
voltage of COUT and the output current of VOUT.

Current Limit Circuit
Current limit circuit supervises the inductor peak current (the peak current flowing through Pch. Tr.) in each
switching cycle, and if the current exceeds the LX current limit (ILXLIM), it turns off Pch. Tr. ILXLIM of the RP509x
is set to Typ.1.6 A or Typ.1.0 A.
Notes: ILXLIM could be easily affected by self-heating or ambient environment. If the VIN drops dramatically or
becomes unstable due to short-circuit, protection operation could be affected.

Operation of Step-down DC/DC Converter and Output Current
The step-down DC/DC converter charges energy in the inductor when LX Tr. turns “ON”, and discharges the
energy from the inductor when LX Tr. turns “OFF” and controls with less energy loss, so that a lower output
voltage (VOUT) than the input voltage (VIN) can be obtained. The operation of the step-down DC/DC converter
is explained in the following figures.

Basic Circuit
Inductor Current (IL) flowing through Inductor (L)
Step1. Pch. Tr. turns “ON” and IL (i1) flows, L is charged with energy. At this moment, i1 increases from the
minimum inductor current (ILMIN), which is 0 A, and reaches the maximum inductor current (ILMAX) in
proportion to the on-time period (tON) of Pch. Tr.
Step2. When Pch. Tr. turns “OFF”, L tries to maintain IL at ILMAX, so L turns Nch Tr. “ON” and IL (i2) flows into L.
Step3. i2 decreases gradually and reaches ILMIN after the open-time period (tOPEN) of Nch. Tr., and then Nch.
Tr. turns “OFF”. This is called discontinuous current mode.
As the output current (IOUT) increases, the off-time period (tOFF) of Pch. Tr. runs out before IL reaches
ILMIN. The next cycle starts, and Pch. Tr. turns “ON” and Nch. Tr. turns “OFF”, which means IL starts
increasing from ILMIN. This is called continuous current mode.
In PWM mode, VOUT is maintained by controlling ton. The oscillator frequency (fOSC) is maintained constant
during PWM mode.
When the step-down DC/DC operation is constant, ILMIN and ILMAX during ton of Pch. Tr. would be same as
during tOFF of Pch. Tr. The current differential between ILMAX and ILMIN is described as ∆I, as the following
equation 1.
∆I = ILMAX − ILMIN = VOUT × tOPEN / L = (VIN − VOUT) × tON / L ·················································· Equation 1
The above equation is predicated on the following requirements.
T = 1 / fOSC = tON + tOFF
duty (%) = tON / T × 100 = tON × fOSC × 100
tOPEN ≤ tOFF
In Equation 1, “VOUT × tOPEN / L” shows the amount of current change in "OFF" state. Also, “(VIN − VOUT) × tON /
L” shows the amount of current change at "ON" state.

Discontinuous Mode and Continuous Mode
As illustrated in Figure A., when IOUT is relatively small, tOPEN < tOFF. In this case, the energy charged into L
during tON will be completely discharged during tOFF, as a result, ILMIN = 0. This is called discontinuous mode.
When IOUT is gradually increased, eventually tOPEN = tOFF and when IOUT is increased further, eventually ILMIN >
0 as illustrated in Figure B. This is called continuous mode.

When tON < tONC, it is discontinuous mode, and when tON = tONC, it is continuous mode.

Forced PWM Mode and VFM Mode
Output voltage controlling method is selectable between a forced PWM control type and a PWM/VFM autoswitching control type, and can be set by the MODE pin. The forced PWM control switches at fixed frequency
rate in order to reduce noise in low output current. The PWM/VFM auto-switching control automatically
switches from PWM mode to VFM mode in order to achieve high efficiency in low output current.
Forced PWM Mode
By setting the MODE pin to “H”, the IC switches the frequency at the fixed rate to reduce noise even when the
output load is light. Therefore, when IOUT is ∆IL/2 or less, ILMIN becomes less than “0”. That is, the accumulated
electricity in CL is discharged through the IC side while IL is increasing from ILMIN to “0” during ton, and also
while IL is decreasing from “0” to ILMIN during tOFF.
VFM Mode
By setting the MODE pin to “Low”, in low output current, the IC automatically switches into VFM mode in order
to achieve high efficiency. In VFM mode, ton is determined depending on VIN and VOUT.

Precautions for the Selection of External Parts
•
•
•
•
Choose a low ESR ceramic capacitor. The capacitance of CIN between VIN and GND should be more than
or equal to 4.7 µF. The capacitance of a ceramic capacitor (COUT) should be 10 µF. Also, choose the
capacitor with consideration for bias characteristics and input/output voltages. See the above tables of
“Input Voltage vs. Capacitance” and “Set Output Voltage vs. Capacitance”.
The phase compensation of this device is designed according to the COUT and L values. The inductance
range of an inductor should be between 0.47µH to 0.56 µH in order to gain stability. See the above table of
“Inductance Range vs. PWM Frequency”.
Choose an inductor that has small DC resistance, has enough permissible current and is hard to cause
magnetic saturation. If the inductance value of the inductor becomes extremely small under the load
conditions, the peak current of LX may increase along with the load current. As a result, over current
protection circuit may start to operate when the peak current of LX reaches to LX limit current. Therefore,
choose an inductor with consideration for the value of ILXMAX. See the following page of “Calculation
Conditions of LX Pin Maximum Output Current (ILXMAX)”.
As for the adjustable output voltage type (RP509x00XC/RP509x00XD), the set output voltage (VSET) can
be arbitrarily set by changing the vales of R1 and R2 using the following equation: VSET = VFB × (R1 + R2) /
R2
Refer to the following table for the recommended values for R1, R2 and C1.

Calculation Conditions of LX Pin Maximum Output Current (ILXMAX)
The following equations explain the relationship to determine ILXMAX at the ideal operation of the ICs in
continuous mode.
Ripple Current P-P value is described as IRP, ON resistance of Pch. Tr. is described as RONP, ON resistance of
Nch. Tr. is described as RONN, and DC resistor of the inductor is described as RL.
First, when Pch. Tr. is “ON”, Equation 1 is satisfied.
VIN = VOUT + (RONP + RL) × IOUT + L × IRP / tON ·································································· Equation 1
Second, when Pch. Tr. is "OFF" (Nch. Tr. is "ON"), Equation 2 is satisfied.
L × IRP / tOFF = RONN × IOUT + VOUT + RL × IOUT ·································································· Equation 2
Put Equation 2 into Equation 1 to solve ON duty of Pch. Tr. (DON = tON / (tOFF + tON)):
DON = (VOUT + RONN × IOUT + RL × IOUT) / (VIN + RONN × IOUT − RONP × IOUT) ······························· Equation 3
Ripple Current is described as follows:
IRP = (VIN − VOUT − RONP × IOUT − RL × IOUT) × DON / fOSC / L ················································· Equation 4
Peak current that flows through L, and LX Tr. is described as follows:
ILXMAX = IOUT + IRP / 2 ································································································· Equation 5

TECHNICAL NOTES
The performance of a power source circuit using this device is highly dependent on a peripheral circuit. A
peripheral component or the device mounted on PCB should not exceed its rated voltage, rated current or
rated power. When designing a peripheral circuit, please be fully aware of the following points.
•
Set the external components as close as possible to the IC and minimize the wiring between the
components and the IC. Especially, place a capacitor (CIN) as close as possible to the VIN pin and GND.
•
Ensure the VIN and GND lines are sufficiently robust. If their impedance is too high, noise pickup or unstable
operation may result.
•
The VIN line, the GND line, the VOUT line, an inductor, and LX should make special considerations for the
large switching current flows.
•
The wiring between the VOUT pin and an inductor (L) (RP509xxxXA/RP509xxxXB) or between a resistor
for setting output voltage (R1) and L (RP509x00XC/RP509x00XD) should be separated from the wiring
between L and Load.
•
Over current protection circuit may be affected by self-heating or power dissipation environment.
•
For any setting type of output voltage, the input/output voltage ratio must meet the following requirement to
