  • ADP1621 circuit review request

    Hello I am trying to boost it using the ADP1621.
    I am trying to output 9V and 2A~3A for 3.5~4.2V input (Li-po Battery).
    I tried making the circuit, but it doesn't work well.
    Is the circuit element value wrong? Please review


  • RE: ADP1621 Sepic & Cuk Design Poor Efficiency

    Hi Fil

    Thanks for post

    So I've tried a lot of different parts in LTSpice and Reality. And now it works really perfect. The best efficiency is about 92% - and the EMI is absolutely satisfying.

    So thanks again for your help

    best regards
