Description
The RH5RH331A-T1 is a PWM Step-up DC/DC converter IC by CMOS process. It consists of an oscillator, a PWM control circuit, a driver transistor, a reference voltage unit, an error amplifier, a phase compensation circuit, resistors for voltage detection, a soft-start circuit, and an Lx switch protection circuit. With only an inductor, a diode, and a capacitor as external components, a low ripple, high-efficiency step-up DC/DC converter can be constructed using this IC. The RH5RH331A-T1 achieves ultra-low supply current of 15µA with no load, thanks to a newly developed PWM control circuit.
