Datasheet

7.0V〜28V Input, 3A Integrated MOSFET

Single Synchronous Buck DC/DC Converter

BD9E302EFJ

BD9E302EFJ is a synchronous buck switching regulator

with built-in power MOSFETs. High efficiency at light load

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.
