4.0V(or 4.5V) to 5.5V, 0.8A 1ch

Synchronous Buck Converter Integrated FET

BD9102FVM BD9104FVM

General Description

Key Specifications

The BD9102FVM and BD9104FVM are ROHM’s high

efficiency step-down switching regulator designed to

produce a voltage as low as 1.24V from a supply

voltage of 5V. Offers high efficiency with our original

pulse skip control technology and synchronous

rectifier. It offers high efficiency by using synchronous

switches and provides fast transient response to

sudden load changes by implementing current mode

control.
