Sharp LC26, LC32 and Sharp LC37 – LCD TVs – SMPS and back light inverter schematics

FD605WJ (POWER SUPPLY UNIT - NJM2904M, MR4020, TXA037WJ 

IC704: POWER SUPPLY CONTROLLER FOR INVERTER
MR4020 (26”) / MR4030 (32”/37”)
Sharp code: VHIMR4020++-1 / VHIMR4030++-1
A high speed 900V IGBT makes ideal partial resonance operation which ensures high efficiency and low noise.
Very low power consumption at micro-loads (burst mode).
Start-up circuit eliminates the need for start-up resistor.
Excess current protection (ON period limitation, primary current limitation), excess voltage protection, and thermal shut-down function are incorporated.
