Datasheet
7.0V28V Input, 3A Integrated MOSFET
Single Synchronous Buck DC/DC Converter
BD9E302EFJ
General Description
BD9E302EFJ is a synchronous buck switching regulator
with built-in power MOSFETs. High efficiency at light load
with a SLLMTM (Simple Light Load Mode). It is most
suitable for use in the equipment to reduce the standby
power is required. It is a current mode control DC/DC
converter and features high-speed transient response.
Phase compensation can also be set easily.
