Description

The EVL185W-LEDTV is a high-end

demonstration board tailored to the specifications

of a typical LED TV application. The peculiarities

of this design are the very high average efficiency

of about 90%, without synchronous rectification,

and very low no load consumption of 100 mW at

230 Vac. The result is that this converter is

compliant to the most demanding ENERGY

STAR

up of two sections, based on a three-stage

approach: a 10 W standby supply using the new

VIPer27L, which delivers the 5 V standby

dedicated to supplying the microprocessor and

the logic circuitry, and a bigger section composed

of a front-end PFC, using the new TM L6564 and

an LLC resonant converter, using the L6599A,

delivering three output voltages: 12 V dedicated

to supplying the TV panel, 24 V to supplying the

audio power amplifiers, and 130 V dedicated to

the backlight.

The PFC stage delivers 400 V constant voltage

and acts as the pre-regulator for both the LLC

stage and the standby supply.

An external signal, referred to secondary ground,

turns the PFC and the LLC stage on and off.
