Hi folks,
I have here some nice LED panel power supply and I want to hack in. But I cannot found anything about this control chip.
It look like something fairly new and using modern topology.
It have no input capacitor just PFC choke and single discrete transistor to switch
And it is all digitally controlled by MSP430 trough I2S bus (with CC2500 wireless chip)
Regulation is done from primary side to constant current output
Chip marks:
