Hi,
I asking the community to choose b/w UCC28711 vs UCC28740. Here is my parameters
Vin = 100v to 500v ( Solar Application, voltage varies)
Output= 24v, 0.5 amps and 15v, 0.6 amps
Topology= Flyback
The difference I got is that UCC28740 has opto feedback additional to UCC28711. What I liked about UCC28711 is that it has good reference design for 400-1000V input power supply.
Anybody can shed some light on choosing between these two ?
