Description

The STEVAL-ISA008V1 demonstration board is a

28 W switch mode power supply which can be

used to supply an LCD monitor or even an LCD-

TV, with 15" or 17" panels and 2 lamps for

backlight together with multimedia functions such

as audio. The SMPS accepts a full range input

voltage (90 to 265 Vrms) and can deliver four

output voltages dedicated to the scaler (3.3 V), to

the mP (7 V), to the backlight and audio (12 V),

and to the TV tuner (35 V).

Doc ID 18217 Rev 1

The standby performance is very good, and the

power consumption during standby is 800 mW at

230 Vac.

The circuit is also fully protected against faults

such as output short-circuit or overvoltage.

The design pays particular attention to the final

cost of the solution, so the PCB has been

designed as single layer, and the circuit has no

heat sink. The technology used is the standard

through-holes, but can be easily changed to SMT

as most of the components are available also in

this technology. The circuit has been tested

thoroughly in all the most relevant aspects with

positive results and has been integrated with a

15" LCD-TV application without showing any

problems.
