2.7V to 5.5V, 3A 1ch

Synchronous Buck Converter with

Integrated FET

BD8963EFJ

General Description

Key Specifications

The BD8963EFJ is ROHM's high efficiency step-down

switching regulator designed to produce a voltage as

low as 1.0V from a supply voltage of 5.5V/3.3V. It offers

high efficiency by using synchronous switches and

provides fast transient response to sudden load

changes by implementing current mode control.
