ROHM Semiconductor revealed two new buck DC/DC converter ICs with built-in MOSFET, the BD9G500EFJ-LA and BD9F500QUZ.

The BD9G500EFJ-LA and the BD9F500QUZ are ideal for applications supporting high voltages and currents in factory automation. 

The BD9G500EFJ-LA with built-in MOSFET offers an 80V withstand voltage for 48V power supply systems, while the BD9F500QUZ with built-in Nano Pulse Control™ technology provides 39V withstand voltage and 5A output current in a compact package.

According to ROHM, application examples include:

  • Servers
  • Charging stations 
  • Power amps 
  • Electric bicycles 
  • Power tools
  • Home appliances 


  • Surveillance cameras
  • PLCs 
  • Inverters
  • FPGAs 
  • SoCs installed in various industrial equipment
