RP506K Series

2 A PWM/VFM Step-down DC/DC Converter with Synchronous Rectifier

NO.EA-296-160523

OUTLINE

The RP506K is a low supply current CMOS-based PWM/VFM step-down DC/DC converter with synchronous

rectifier featuring 2 A

(1)

output current. Internally, a single converter consists of an oscillator, a reference voltage

unit, an error amplifier, a switching control circuit, a mode control circuit, a soft start circuit, a latch type

protection circuit, an under-voltage lockout (UVLO) circuit, a thermal shutdown circuit, and switching transistors.

The RP506K 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.

Power controlling method can be selected from forced PWM control type or PWM/VFM auto switching control

type by inputting a signal to the MODE pin. In low output current, forced PWM control switches at fixed

frequency rate in order to reduce noise. Likewise, in low output current, PWM/VFM auto switching control

automatically switches from PWM mode to VFM mode in order to achieve high efficiency.

Output voltage type can be selected from an internally fixed output voltage type (RP506Kxx1A/B/D/E) or an

externally adjustable output voltage type (RP506K001C/F). The output voltage of the RP506Kxx1A/B/D/E can

be set by 0.1 V step and the output voltage accuracy is as high as ±1.5% or

±18

mV. The output voltage of the

RP506K001C/F can be set by using the external resistors.

Oscillator frequency can be selected from 2.25 MHz (RP506Kxx1A/B/C) or 1.2 MHz (RP506Kxx1D/E/F). Soft-

start time is Typ. 0.15 ms, and by connecting an external capacitor to the TSS pin, soft-start time is adjustable.

Power good (PG) function monitors the V

OUT

pin voltage or the feedback pin voltage (V

), and switches the

PG pin to low if any abnormal condition is detected.

Protection circuits included in the RP506K are over current protection circuit, latch type protection circuit and

thermal shutdown circuit. Over current protection circuit supervises the inductor peak current in each switching

cycle, and if the current exceeds the L

current limit (I

LXLIM

), it turns off Pch Tr. Latch type protection circuit

latches the built-in driver to the OFF state and stops the operation of the step-down DC/DC converter if the

over current status continues or V

OUT

continues being the half of the setting voltage for equal or longer than

protection delay time (tprot). Thermal shutdown circuit detects overheating of the converter if the output pin is

shorted to the ground pin (GND) etc. and stops the converter operation to protect it from damage if the junction

temperature exceeds the specified temperature.

The RP506K is available in DFN(PLP)2527-10 which achieves high-density mounting on boards.

(1)

This is an approximate value. The output current is dependent on conditions and external components.
