    Please Help Identify this SOT23-6 DC DC converter smd code 200

    Hi guys

    Does anyone know what this component is (see pic)

    marking 200
    package SOT23-6

    it is some sort of DC DC converter, it is from a MAG322 STB, the input is directly from the 12V power jack

    Pin 1 --> Ground
    Pin 2 --> Inductor Coil (Vout)
    Pin 3 --> Vin (12V)

    It has a low resistance 10 ohms from Vin to ground, failed after the incorrect power supply was plugged in, 5V instead of 12V. In my experience the lower voltage seems to kill the chip by making it draw more current in an attempt to generate the correct output

    I thought it may be something like SY8009 but they have max 5.5V in

    Thanks
    Richard
