RH5RH301A-T1 - Brand New STMicroelectronics IC Chips
-
Description
The RH5RH301A-T1 is a PWM Step-up DC/DC converter IC that belongs to the RH5RH××1A/××2B/××3B Series. It is designed using CMOS process technology. The IC features an oscillator, PWM control circuit, driver transistor, 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 - an inductor, diode, and capacitor - this IC can construct a low ripple, high efficiency step-up DC/DC converter. It achieves ultra-low supply current of typically 15µA (no load) due to a newly developed PWM control circuit.
