    STMicroelectronics’ 200W Digital-Power Solution for LED Televisions Beats Toughest Eco-Design Standards

    The STEVAL-NRG011TV board from STMicroelectronics helps designers quickly build 200W digital power supplies and adapters for LED and OLED televisions to exceed the toughest energy efficiency and standby regulations.

    Based on ST’s STNRG011 digital PFC (power factor correction) and resonant LLC converter, the STEVAL-NRG011TV combines a proven and reliable topology with the ability to configure and fine-tune the operating parameters for optimal performance. No coding is needed as the digital control algorithms are permanently programmed in the controller’s ROM and the board comes with a complete set of sample parameters stored in programmable non-volatile memory (NVM).

    The STEVAL-NRG011TV provides a 12V/4A regulated output to power the television’s controller and audio subsystem and a 65V/2.5A output for LED backlighting. The wide AC input voltage range, from 90V to 264V, allows use in power supplies and adapters to be marketed worldwide. The performance goes beyond today’s highest eco-design specifications, achieving full-load efficiency over 91% at 115V and 230V AC and no-load mains consumption below 120mW.

    The STNRG011 at the heart of the board provides a highly integrated solution for power-factor-corrected, high-efficiency converters. Included on-chip is an 8-bit CPU subsystem, control logic including PFC and LLC event-driven state machines (SMEDs), an analog-to-digital converter (ADC), high-voltage startup circuitry, power management, and protection. A two-wire interface handles communication with the external EEPROM as well as remote monitoring and software updates. Housed in a 20-pin SO20 power package, this device enables a simplified board layout and compact dimensions.

    The STEVAL-NRG011TV is available now for $195.00. The STNRG011 is in full production, priced from $1.56 for orders of 1000 pieces.
