The STEVAL-NRG011TV is a 200 W LED TV SMPS providing 12 V regulated output voltage (for MCU supply and audio system applications) and 65 V output voltage for LED back lighting.The design is based on the STNRG011 IC digital combo controller that controls a two-stage AC/DC SMPS. The front-end is a transition mode PFC pre-regulator and the second stage is an LLC HB resonant converter.Thanks to the STNRG011 IC, the user can take full advantage of digital implementation without the need of writing code. A complete set of parameters, stored in the controller non-volatile memory (NVM), allows the configuration and fine tuning of the application.
