Overview
R1232D SERIES PWM STEP-DOWN DC/DC CONVERTER WITH SYNCHRONOUS RECTIFIER NO.
EA-129-130510 OUTLINE The R1232D Series are CMOS-based PWM step-down DC/DC converters with synchronous rectifier, low supply current.
As an output capacitor, a 10μF or more ceramic capacitor can be used with the R1232D.
Each of these ICs consists of an oscillator, a PWM control circuit, a voltage reference unit, an error amplifier, a soft-start circuit, protection circuits, a protection against miss operation under low voltage (UVLO), a chip enable circuit, a synchronous rectifier, Nch.
driver transistor, and so on.
A low ripple, high efficiency step-down DC/DC converter can be easily composed of this IC with only a fe...
