General Description

The BD8964FVM is ROHM’s high efficiency step-down switching regulator designed to produce a voltage as low as 1V from a supply voltage of 5V. It offers high efficiency by using synchronous switches and provides fast transient response to sudden load changes by implementing current mode control.

Features

■ Fast Transient Response because of Current Mode PWM Control System

■ High Efficiency for All Load Ranges with Synchronous Rectifier (Nch/Pch FET)

■ Soft-Start Function

■ Thermal Shutdown and UVLO Functions

■ Short-Circuit Protection with Time Delay Function

■ Shutdown Function

Application

Power Supply for LSI including DSP, Microcomputer and ASIC
