Other Parts Discussed in Thread: LM3880, AM3703

 We have questions about LM3880.

Question 1.

   We try to use LM3880 in the following way.

    Vin=GPIO output of AM3703(1.8V)

   Is the EN pin turned on with the above usage?

Question 2.

    Please tell us the input current of EN pin when EN is High.

Best regards,

Takahiro  Nishizawa

    #1. there is no Vin pin at LM3880. Do you mean Vcc or Ven. For the Vcc, the input must be within 2.7 - 5.5V. for the Ven, the input shall be greater than 1.v

    #2 EN pin has 7uA pull up current.

    Regards
