LM3880: LM3880

Part Number: LM3880

i wanna ask you guys about the resistor devider that could placed with the EN pin.

what it is for ?

how do we choose the values efficiently ?

  • Hi

    There is 7uA current source at the EN pin, you have to take this into consideration when selecting the resistor to ensure that

    Vcc_enable=1.22V[1+(Ren1/Ren2)] - 7uARen1
