BD9S303MUF-C

General Description

Key Specifications

BD9S303MUF-C is a synchronous buck DC/DC Converter

with built-in low on-resistance power MOSFETs. It can

provide current up to 3 A. Small inductor is applicable due

to high switching frequency of 2.2 MHz. It is a current mode

control and features fast transient response. The Light

Load Mode control improves efficiency in light-load

conditions. It is ideal for reducing standby power

consumption of equipment. It has a built-in phase

compensation circuit. Applications can be created with a

few external components.
