The UCC142140-Q1 integrates a high-efficiency, low-emissions isolated DC/DC converter for powering the gate drive of SiC or IGBT power devices in traction inverter motor drives, industrial motor drives, or other high voltage DC/DC converters. This DC/DC converter provides greater than 1.5 W of power across a 3000 VRMS basic isolation barrier. TI also has the newer reinforced isolation device, UCC14341-Q1 that takes in a 15 V input and similarly provides an adjustable isolated output up to 25 V. For an optimized BoM, the UCC14341-Q1 can be directly connected to the 15 V resolver rail that is commonly available in a traction inverter.
