STEVAL-ISA008V1 VIPer53 Low Cost wide range power supply for LCD or TV, 28W Output
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).
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.
