Abstract

TI developed LLC controllers over the past 15 years and also developed the LLC controller (TPS9202X) which dedicates for LED lighting PSU application. TI has several years experience in LLC topology and LED lighting PSU. The previous generation devices UCC256302 also promoted to several key LED lighting PSU customers and receives valuable feedback. This application note is a compilation of lessons learned to develop the UCC25640X product and introduces the UCC25640X benefits in LED lighting PSU.
