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.
