R1232D Datasheet (RICOH electronics) - PWM STEP-DOWN DC/DC CONVERTER

R1232D, PWM STEP-DOWN DC/DC CONVERTER

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 vol
