Identify 6p SMD switching ng ic device

[diag7919]

Hi guys, my battery charger just stopped working, zero life but faint burning smell which I have had a look and done a bunch of diode tests. No shorts, nothing so wondering if the main switching IC has let go.. looks like only 1 secondary with zero volts on the reservoir cap.. fuses all good, I have rectified mains voltage present on the primary cap.. anyway, I have no idea and spent a fair time searching for this ic, has anyone got any ideas.. using my phone I "think" the markings are 63H30a 347..

Thanks

Nick

Check R12 and R13 for open circuits.

Check or replace the capacitor on the IC's Vcc pin (D3 cathode).

Does D2 look like it's cooked?

I believe that's an OB2263.

Thanks guys.. I've got a magnifying eye glass coming for future plus another charger from same brand has stopped working, both being used at my son's house so he has dicky electrics.... I will double check those resistors..
