Backlight inverter driver ic id

Looks like the pinout is as follows, Pins 1 & 3 go to ground, Pins 2 &

Thanks, Steve

Not sure about that part number, but the pinout you describe is pretty standard for a dual N-channel power MOSFET.

FET#1 - S:3 G:4 D:5&6 FET#2 - S:1 G:2 D:7&8

If it's a free-running resonant converter, there might not be any control IC.

I don't know why I couldn't find that, I guess I just didn't search for the right terms. Any idea on how much current these will be switching? It's a 15 inch LCD. Something like the FDS6912 may work, I'll just have to give it a shot. Thanks again, Steve

I think I may have found what you're looking for:

Renesas HAT2215R / HAT2215RJ

Now just keep your fingers crossed that some other part of the inverter didn't die first...

k,

I'll be darned. How the heck did you find that? It doesn't look like they'll do samples & only do large quantity sales. I guess at least I have the data so now I can find a close enough equivalent.

Any thoughts on that?

I'm sure other parts have died. It's hard finding these parts for this TV, I'm used to working on avionics, the parts can generally be purchased in small quantities from a number of sources, it seems like all these parts are made overseas & no one stocks them. Oh well, the price to pay for cheap electronics.

Thanks for your help, I'm amazed you found it.

ork,

I'm no component expert, which is why I'm asking for help. How about the FDS3812? Looks like a close match, I would think it'd be ok for a backlight inverter.

Looks like I spoke too soon, no one will sell less than a few thousand of these either.

I'd say your component skills look just fine...

Have you tried Mouser?

I must be blind. I could have sworn Mouser didn't stock it. That's great news, we order from them at least once a week. Sorry for the irresponsible posting.

Thanks for all your help everyone.
