Description
The RH5RH501A-T1-F is an electronic component model that falls under the product category of IC chips. It is a PWM Step-up DC/DC converter IC manufactured using CMOS process. This IC is comprised of various components such as 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. With just three external components, namely an inductor, a diode, and a capacitor, this IC is capable of constructing a low ripple, high-efficiency step-up DC/DC converter. The RH5RH501A-T1-F boasts ultra-low supply current, typically 15µA, thanks to a newly developed PWM control circuit.
