    What is this SOT23-5

    I have a home decorator fan that use DC motor
    In the controller there is what i believe some kind of power regulator in an SOT23-5 format
    I receive 170vdc that comes from the 120vac rectified
    It has as few components around like resistor and capacitor and diode
    On the top it has the letter IAFAK and in the bottom says C278
    Any idea what is that? I would like to find the data sheet for it

      Could be a MPS MP156GJ

              Moding a 120vAC smps to work with 220vAC
              by madan1
              Hello everyone.
              So basically the question is in the title - is it possible to mod a 120vAC switching mode power supply unit to work with 220-240vAC?
              The particular unit is the one from the photos.

              It looks like someone ignored the 120vAC label and plugged it in 240vAC. According to the user - "it every time tripped the fuse".
              The only visible damage is the high voltage smoothing cap, which has vented quite energetically ( everything above it is sprayed with goo ), but did not explode.
              The thru-hole components on the primary side measure fine...

              Samsung UN60EH6000 wont come on after lightning strike.
              by karthur
              We had a lightning strike a few days ago really close to my house. My Samsung UN60EH6000 was on when it hit. Afterwards, the TV would not come back on.

              I had repaired this TV a few years back by replacing the T-Con board. (The post I had on this is repair is here.)

              When I turn on the TV, I don't get any start-up melody. The screen just dimly flickers around the edges.

              Here is what I have checked.
              On the power supply board, 14pin connector:
              1 :12.7 Vdc
              3 :12.7
              5 :12.7
              7 :12.7
              9 :0
              11 :5.
              13 :5....

              I think about buying one of them I would like to know if anyone has used this device before and what you think about it

              Using Kynar 30AWG for 120VAC
              by eccerr0r
              I saw this and

              Granted this looks like a homebrew and at least 30AWG wire should fuse on its own if it shorts out......

              Stagg sms12p audio amp has water damage
              by edugimeno
              Hi! My friend just brought this audio amplifier/speaker fro his music band saying they realized its got no sound. Led powers up but there no sound at all
              I opened it and found 3 board. 2 of them are for input plugs and potentiometers, and the other larger board has the amplifiers for 2 large speakers that it drives
              There's also a large toroid transformer that feeds a lower voltage to the first 2 boards and a larger voltaje (36x2 rectified close to 100v) to the power board. The power board has the plugs for both speakers
              There is only one signal wire connecting the first boards...
