PMP40182: how to change to 0~15V & -5~5A ?

Part Number: PMP40182

Dear TI Expert,

PMP40182's Original desgin is 0~4V & -10~10A. My customer want to change PMP40182 to meet 0~15V & -5~5A , could you kindly help to advise which parameter should be adjusted? Thanks a lot.

  • Hi, Bruce,

    Thank for your promotion on PMP40182, I split the changes into three blocks, please check it, thanks.
    Voltage related circuit change:
    1. output overvoltage point need to be changed. R8 and R20
    2. U10A sensing the output voltage parameters. R55,R57,R62,R67,
    Current related circuit change:
    1. current sense resistor. R1 change to 4mohm
    Power components:
    1. L2 inductor need to be chagned.
    2. C9,C1,C2,C10,C11 capacitor rated voltage need to be increased above 16V;
    3. Q3,Q4 rated voltage need to be chagned according to derelated requirement.
    4. if input voltage is increasing, please change the input MOSFET and capacitor rated voltage.
  • Dear David,
    Got it,thank you so much for the detailed guide.
