LMG1020: pinmap

Zichao Guo

Part Number: LMG1020

I can not recognize the pinmap of the LMG1020. I do not know which pin is the pin-1 in the datasheet. There are only a few letters on the top of the package, may be 4 letters. Is there anyone here who can help me?

Hi Zichao,

You can see there is an "X" close to the right upper side of this photo. That is pin 1 (A1).

Thanks and regards,

Are you sure about this？ I welded the LMG1020 according to the pinmap just as you said, but the output is a constant 5V voltage when I connected the PIN1 to 5V, PIN2 to GND, PIN3 to 50% PWM, PIN4 to GND, PIN5 to PIN6. Do you know why?

Hi Zichao,

Yes I am sure about it. Please make sure that the pinout map is top viewed, and also make sure that you have good connection during soldering.

Thanks and regards,
