General Description
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.

FEATUREs
■ Offers fast transient response with current mode PWM control system.
■ Offers highly efficiency for all load range with synchronous rectifier (Nch/Pch FET)
■ Incorporates soft-start function.
■ Incorporates thermal protection and ULVO functions.
■ Incorporates short-current protection circuit with time delay function.
■ Incorporates shutdown function

APPLICATIONs
    Power supply for LSI including DSP, Micro computer and ASIC
