OUTLINE
The RH5RH××1A/××2B/××3B Series are PWM Step-up DC/DC converter ICs by CMOS process. The RH5RH××1A IC consists of 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. A low ripple, high efficiency step-up DC/DC converter can be constructed of this RH5RH××1A IC with only three external components, that is, an inductor, a diode and a capacitor. These RH5RH××1A/××2B/××3B ICs can achieve ultra-low supply current (no load) –TYP. 15μA –by a new ly developed PWM control circuit, equivalent to the low supply current of a VFM (chopper) Step-up DC/DC converter.
