Description
The RH5RH503B-T1 is a PWM Step-up DC/DC converter IC by CMOS process. It is part of the RH5RH××1A/××2B/××3B Series. This IC consists of an oscillator, PWM control circuit, driver transistor (Lx switch), reference voltage unit, error amplifier, phase compensation circuit, resistors for voltage detection, soft-start circuit, and Lx switch protection circuit. With only three external components (inductor, diode, and capacitor), it can construct a low ripple, high efficiency step-up DC/DC converter.
