●General Description

●Key Specification

ROHM’s high efficiency step-down switching regulator

BD8963EFJ is a power supply designed to produce a

low voltage including 1 volts from 5.5/3.3 volts power

supply line. Offers high efficiency with synchronous

rectifier. Employs a current mode control system to

provide faster transient response to sudden change in

load.
