R1232D SERIES
PWM STEP-DOWN DC, DC CONVERTER WITH SYNCHRONOUS RECTIFIER
NO.EA-129-0606
OUTLINE
The R1232D Series are CMOS-based PWM step-down DC, DC converters with synchronous rectifier, low supply current. As an output capacitor, a 10 F 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
