Hi all
I have power supply project around 1k5watt output power. I've ever consider to use phase shifted topology, but the primary inductance for my application will be around 2.2mH ( i use SLUC222D.xlx ) which is around 10 times bigger then desired primary inductance in LLC full bridge.
Than i consider to use UCC256404 but due to the power needed, around 1K5 watt, i consider to use full bridge instead of half bridge. Unfortunately, UCC256404 have Vcr pin to detect the resonant cap voltage to ground, which is not suitable for full bridge topology, since the capacitor will not connect to ground anymore.
How to use ucc 256404 for full bridge LLC? Or do TI have suitable LLC resonant controller that is suitable for full bridge topology?
thanks and regards
