Isolated DC-DC converters provide asymmetric output for gate drives

October 1, 2026

Offering isolated power outputs for high-side and low-side gate drive circuits, the Murata MGJ1 series of 1W DC-DC converters are suitable for silicon carbide (SiC), IGBT, and MOSFET bridge circuits.

The MGJ1 series from Murata are DC-DC converters featuring high isolation typically required by bridge circuits used in motor drivers and inverters. The DC-DC converters have an industrial-grade temperature range between -40°C to 115°C and are surface-mounted.

 

The MGJ1 offers asymmetric voltage outputs to improve switching efficiency, optimized for IGBT, SiC, and MOSFET gate drives. Three output options are available:

  • 15W/-3V
  • 15V/-5V
  • +18V/-2.5V

 

Reliability has been evaluated through extensive environmental testing, including 1,000 temperature cycles between -40°C and 125°C, as well as humidity, vibration, shock, and ESD testing in line with JEDEC standards.  

 

The MGJ1 series is patent-protected, rated for long service life and reliability.

Features

  • 12V, 15V & 24V inputs 
  • Ultra-low isolation capacitance 
  • Continuous barrier withstand voltage 2.2kV DC 
  • UL62368-1 recognised

Applications

  • Motor drives and industrial inverters
  • Medical power supplies
  • Solar power inverters
  • Industrial drives

Part Number: MGJ1
