Description
The RH5RH401A-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 (Lx switch), 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. This IC is capable of constructing a low ripple, high efficiency step-up DC/DC converter with only three external components: an inductor, a diode, and a capacitor. It achieves an ultra-low supply current of TYP. 15µA with no load, thanks to a newly developed PWM control circuit.
