Buck Boost Converter circuit +12 V input voltage (10v. .25 there may be between)-13v as a favor from the (inverting) power 250mA optionally output voltage D2 zener diode changing can be increased or reduced (5v … 20v) circuit operating frequency of 12kHz pcb design (sprint layout) done according to the size quite small sMD components

NCP1606B Power Factor Controller NCP1351B Switch Mode Power Supply
LCD TVs, monitors the use of devices is constantly evolving quite common image quality, additional features, etc.. is increasing with each passing day since the early days, one of the most important parts in solid SMPS inverter is still continually being developed, but I’ve seen most failures solid parts SMPS ..
This practice 180w pfc li (NCP1606B power factor pfc controller) inverter SMPS (NCP1351B Variable Off Time PWM Controller) circuit design from start to finish, schemes formulated and is described (in english) quite a useful document
