IC trying to identify from ST

hi all,

I'm trying to identify a component on a small AC/DC power module. It's an 8 pin surface mount IC made by STMicoelectronic and it has two identification markings

1) ST E 9615 (the E doesn't look like a capitol E, it almost looks like a £ symbol?)

2) 33428 (the second digit 3 could be an 8)

If you have an help on where i can look or better still if you recognize this component would you let me know.
kind regards
Marcus

 

Hi there, thanks for your replies. It's quite exciting getting back into electronics from a gap of 15 years and with forums like these. Appreciate any feedback.
Attached should be the IC I'm trying to check. There is a resistor or something burnt out too but I thought if I can look to see what the chip is doing and I may be able to determine what the component is and its value.
Thanks for your help and I'll check out the ST website.
Kind regards
Marcus

 

thanks Dave, i think you are right. The component just above the chip is completely burnt out. I was hoping to determine what it could be and it's value based off the LM334 but i will need to do more studying attached is the component in question.
thanks again for your help

That's right, Big Bang !! My plan is to replace what I think didn't make it after the bang then start with a very high resistor and work down until it works. The module is an AC to DC converter with 4 DC outputs. I'll try and map the circuit and post it on here. That'll keep me busy for a while.
Thanks
Marcus
