Hi guys can anyone identify this please
It's in a 1500W ATX PSU
Marking looks like BC729 or 8C729 but the B or 8 is a funny symbol with the top ha1lf smaller than the bottom half
I suspect it is a voltage regulator
The centre pin/tab goes to ground
The right pin goes to a CM6902 PWM chip VCC pin and only has 0.5V
The left pin has 0V but I think it should go to a 16V rail on the 5V STB
transformer but the PCB is too densely populated to see how it would get there on the other side.
On this side it only goes to two capacitors in parallel, the other end of the caps goes to ground. These look like they are input caps to me
best regards
Richard
