QuiCur™, Nano Pulse Control™, 2.7V to 5.5V Input, 3A Single Synchronous Buck DC/DC Converter for Automotive
BD9S303MUF-C is a synchronous buck DC/DC Converter with built-in low on-resistance power MOSFETs. It can provide current up to 3A. Small inductor is applicable due to high switching frequency of 2.2MHz. 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.
