Component identification help

[matt09]

Is anyone able to help identify these components, I've had a look around but not managed to find anything.
The IC is PWM waveform generator and diode likely some high voltage rectifier.

Thanks

Cheers, I thought I'd checked on there but must have missed it.
Still struggling on the IC.

It might help if we could see the IC in the context of its surroundings. That could help us to identify the date codes and a possible manufacturer.

I'm not too sure it would be useful as it's just a PWM generator chip which feeds a FAN7384 Half Bridge gate drive IC. There are no other active components for this circuit except the FETs, unless you think other circuits on the board might be helpful?

Could it be a preprogrammed 8-pin microcontroller?

Something like a PIC12F629/675?

Which pins are Vcc and Ground? Which pins connect to HIN and LIN of the gate driver?
