12.2.3 Application Curves

The UCC15241-Q1 has the same pinout and functionality as the UCC14240-Q1, with a different maximum output power capability. The application response will be similar and the PMP23223 reference design is still valuable to demonstrate the capability. The PMP23223 is a reference design that pairs the complementary UCC14240-Q1 isolated DC/DC power module with the UCC21732-Q1 isolated gate driver for a SiC power MOSFET or IGBT power module. The following waveforms show the controlled soft start for both positive and negative rails. Also shown, is the fast and highly accurate voltage regulation during gate driver switching from 1 kHz to 35 kHz. See PMP23223 reference design test report for more details.
