com 2CH PWM DC/DC CONTROLLER R1282D002A SERIES OUTLINE NO.
EA-086-0502 The R1282D002A is a CMOS-based 2-channel PWM Step-up (as Channel 1)/Step-down (as Channel 2) DC/DC converter controller.
The R1282D002A consists of an oscillator, a PWM control circuit, a reference voltage unit, an error amplifier, a reference current unit, a protection circuit, and an under voltage lockout (UVLO) circuit.
A high efficiency Step-up/Step-down DC/DC converter can be composed of this IC with inductors, diodes, power MOSFETs, resisters, and capacitors.
Each output voltage and maximum duty cycle can be adjustable with external resistors, while soft-start time can be adjustable with external...
