General Description

This is the product guarantees long time support in

Industrial market.

BD9G201EFJ-LB is a buck converter with built-in high

side MOSFET. It has an input voltage range of 4.5V to

42V. Current mode architecture provides fast transient

response and a simple phase compensation setup.

The IC is mainly used as a secondary side power

supply: for example, a step-down output of 3.3V/5V can

be produced from voltage power supply such as 12V or

24V. In addition, it has a synchronization function with

an external CLK that provides noise management.
