RP600 Series
500mA PWM/VFM Step-up DC/DC Converter with VD and LDO
RP600 Series are PWM/VFM control step-up DC/DC converters equipped with voltage detector and LDO regulator featuring 500mA output. Step-up DC/DC convertor part has a soft-start circuit. A high-efficiency step-up DC/DC converter can be easily configured by using an inductor, capacitors, a diode as external components. By inputting a signal to MODE pin, RP600 can choose PWM control or PWM/VFM auto switching control. RP600 has the thermal shutdown circuit and small DFN(PLP)2527-10 package is available.

Technical Documents
RP600K0xxA Block Diagram
DC/DC converter; Fixed output voltage.
Voltage Regulator; Power supply is the output of the DC/DC converter. Fast MODE only.
Voltage Detector; "L" output at the detector threshold. With a released output delay time, the hysteresis is fixed 5% of the detector threshold.
RP600K0xxB Block Diagram
DC/DC converter; Fixed output voltage.
RP600K2xxC Block Diagram
DC/DC converter; Fixed output voltage.
Voltage Regulator; Power supply is the output of the DC/DC converter. Regardless of the CE signal, always turns on. When the DC/DC converter is active, regardless of the MODE signal, the mode is fixed as fast mode.
Voltage Detector; "L" output at the detector threshold. Without a released output delay time, the hysteresis can be set in the range from 30% to 80% of the detector threshold. No thermal protection circuit.
RP600K1xxD Block Diagram
DC/DC converter; Adjustable output voltage.
Voltage Regulator; Power supply is the output of the DC/DC converter. Fast Mode only.
Voltage Detector; "L" output at the detector threshold. With released output delay time, the hysteresis is fixed 5% of the detector threshold.
