    Can't find these IC!

    I planned on reworking the amplifiers for my '96 Voyagers speaker setup, but I can't find information on the IC's. The main one is an NEC 9547A and is a 12-pin SIP or whatever. The other is an unbranded BH715H1 (an 8-pin SIP) which leads to the rear speakers, I believe and is used for low low frequency production.

    Anybody, have any rare datasheets? lol!

          Are there 2 rows of numbers on the chips? The 9547A sounds like 1995, 47th week, which would make sense in a 1996 vehicle.

              Where to find a very small fpc connector 0.3mm between 2 pins ?
              by corrize
              Hello, I search this connector (oxydated).
              It's a fpc zif low profile connector. It come from camera sensor, it is very small : 0.3mm between 2 pins.
              I ordered 2 from Aliexpress called « 0.3mm pitch » but one was 0.5mm between 2 pins and the other 0.6mm. In fact « 0.3mm pitch » seams to be the pad width and not the distance between 2 pins.
              I can't find it. The other websites like mouser dont show the datasheet, and I can't check if it is 0.3mm between 2 pins ?

              Do you know how to find this connector please ? What is the exact name for find it ?

              Sentey ATX PSU - ERP650-PS - Trying to find out the right Standby IC
              by temyth
              Greetings! I have this ERP650-PS atx power supply, it is a relatively simple psu, the primary has a driver IC that controls the two main mosfets (two 20n60S5), together with a Classic Standby circuit with a PWM IC (not a FET like the VIper22A) , relatively similar to the SDC606P.

              The whole point is that I got this power supply years ago when I had no knowledge, apparently the PWM IC was burned because someone turned the power supply on with the switch at 110v in a 220v network (classic error). Important detail: the power supply at the time came without the primary capacitors.
