Re: Someone have schematic to Apple iMac Power Supply
hi. can you please help me. what is this NTC31 in a adp-200dfb power supply on imac 1311? is this a thermistor? i accidentally crack it when i removed the transistor heatsink of Q2.
Re: Someone have schematic to Apple iMac Power Supply
I'm also looking for Power Supply Schematic with boardview for ADP-200DFB (iMac A1311) or datasheet for IC31, DAP017A (PFC I think) and or datasheet for IC32, DAP015A (PWM controller I think). In this case I found:
F1 open
Bridge rectifier, BD1, T4KB80F is shorted.
Q2, SPA15N60C3, appears to test good.
Q1,Q3, SPA07N60C3 open.
I've replaced the bad parts but still don't see any PFC boost. My usual debugging approach relies on having a rough idea, from either datasheet application schematics or the actual PSU schematic, of the PSU configuration. In this case I'm stumped. Any suggestion of how to proceed would be welcome.
