Circuit Description
13-2 Samsung Electronics
13-2 Partial Block Description
13-2-1 Main SMPS
1. Outline (PDP 42inch/50inch SMPS)
Considering various related conditions, the switching regulator with good efficiency and allowing for its small size and light weight
was used as the power supply for PDP 42inch/50inch, VS requiring high power consumption Asymmetrical Half Bridge converter
and flyback converter. To comply with the international harmonics standards and improve the power factor, active PFC(Power
Factor Correction) was used to rectify AC input into +400V DC output, which in turns used as input to the switching regulator.
2. Input
The power supply shall be capable of supplying full rated output power over free voltage ranges that are rated 100 VAC - 240 VAC
RMS nominal. Operating voltage : 90 VAC - 264 VAC
The power supply must be able to start up under peak loading at 90V AC. The power supply shall automatically recover from AC
power loss. (Note that nominal voltages for test purposes are considered to be with +/- 1.0V of nominal).
STD_5V & Vpr2(3.3V) is a SELV standby voltage that is always present when AC mains voltage present.
3. Output
① Over Voltage Protection
The over voltage sense circuitry and reference shall reside in package that are separate and distinct from the regulator control
circuitry and reference. No single point fault shall be able to cause a sustained over voltage condition on any of all outputs.
The supply shall provide latch-mode Over Voltage Protection as defined below.
