Description
The RH5RH652B-T1-F is a PWM Step-up DC/DC converter IC, which is a member of the RH5RH1A/2B/3B series. These ICs are manufactured using a CMOS process and can construct a high efficiency, low ripple step-up DC/DC converter with only three external components, including an inductor, a diode and a capacitor. The RH5RH652B-T1-F IC contains an Lx switch, a reference voltage unit, an oscillator, a phase compensation circuit, an error amplifier, resistors for voltage detection, a PWM control circuit, a soft-start circuit and an Lx switch protection circuit. These ICs offer an ultra-low supply current of TYP. 15µA at no load through a newly developed PWM control circuit.
