Description

BD9S402MUF-C is a synchronous buck DC/DC converter with built-in low ON resistor power MOSFETs. It can provide current up to 4A. Small inductor is applicable due to high switching frequency of 2.2MHz. It has fast transient response performance due to current mode control. It has a built-in phase compensation circuit. Applications can be created with a few external components.
