0 描述 The PMP20289 was built and tested to verify the performance of a high frequency (>400kHz nominal switching frequency) LLC series resonant converter (LLC-SRC) implemented with Texas Instrument’s high voltage GaN FETs under nominal (390V to 12V) voltage conversion. The digital controller (...) 主要特色 400V – 12V/500W high frequency LLC series resonant converter 350kHz resonant frequency and 500kHz switching frequency at 400V to 12V conversion Utilize TI high voltage direct drive GaN FETs as input switches Optimized LLC SR conduction with UCD7138/UCD3138A Achieve peak 96.8% efficiency 0 PMP20289 Schematic.pdf 1.05 MB , 下载次数: 26 PMP20289 Schematic LMG3410 (from PMP20047).pdf 111.04 KB , 下载次数: 11 PMP20289 Schematic XFMR (from PMP12047).pdf 86.75 KB , 下载次数: 10 PMP20289 Schematics Control Card (from PMP11432).pdf 129.16 KB , 下载次数: 10
