Description
The R1223N152H is a PWM step-down DC/DC Converter controller with low supply current by CMOS process. It consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a soft-start circuit, a protection circuit, a PWM/VFM alternative circuit, a chip enable circuit, and resistors for voltage detection. This IC can easily compose a low ripple, high efficiency step-down DC/DC converter with only four external components: a power-transistor, an inductor, a diode, and a capacitor.
