Power Management (PMIC)

isolated DC/DCgate driver biasAEC-Q100reinforced isolationSiCIGBTGaN1.5 W

UCC14131QDWNRQ1 is an AEC-Q100 qualified isolated bias-power module for gate-driver supplies, providing adjustable 10 V to 18 V output from a 10 V to 18 V input range.

Best for

  • Compact isolated gate-driver bias supplies
  • Automotive SiC, IGBT, GaN, and MOSFET power stages
  • Applications requiring reinforced isolation targets

Avoid if

  • Output demand exceeds the thermally derated 1.5 W capability
  • The required input voltage is outside 10 V to 18 V
  • Certification status cannot meet the final equipment requirement

Check before use

  • Confirm thermal derating at the final board layout and ambient temperature
  • Validate VDD-VEE and COM-VEE resistor-divider settings
  • Keep copper out of the specified isolation barrier area
  • Do not enable gate-driver PWM before PG indicates valid output
