  • 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


  • ADP1621 Sepic & Cuk Design Poor Efficiency

    Hello

    I'm using two ADP1621, One for a Sepic and one for a Cuk Analog PowerSupply Board

    The parameters are:

    Vin: 9-15VDC

    Vout1: 13.5VDC  (Sepic)

    Vout2: -13.5VDC (Cuk)

    Iout1&2: 2A

    First i designed the circuit with ADIsim - with this created circuit…
