RH5RH332B-T1 - Brand New STMicroelectronics IC Chips
-
Description
The RH5RH332B-T1 is a PWM Step-up DC/DC converter IC by CMOS process. It is a member of the RH5RH××1A/××2B/××3B Series, and it is suitable for use in electronic devices and equipment that require DC voltage conversion. The IC comprises 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. It achieves ultra-low supply current, equivalent to that of a VFM (chopper) Step-up DC/DC converter.
