2.7V to 5.5V, 2.0A 1ch

Synchronous Buck Converter Integrated FET

BD8960NV

●General Description

ROHM’s high efficiency step-down switching

regulator BD8960NV 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
