Overview

BD9G401EFJ 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.

Applications

Consumer devices in general that has 12V / 24V lines
Automotive applications (Audio system, Navigation system, etc)
Industrial distributed-power applications
Entertainment equipment

Key features
