BD9G401EFJ  
General Description  
Key Specifications  
Input Voltage:  
BD9G401EFJ is 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.
