General Description

Key Specifications

BD9G201EFJ-M and BD9G201UEFJ-M are buck

converters 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.
