MIC45212 Current Sharing Reference Design

Part Number: ARD00777

​The MIC45212 Current Sharing Ref. Design improves the current capability of the MIC45212 from 14A to 28A while also decreasing the response time and improving load transient response. This is achieved by paralleling two MIC45212 with one working as a master and the other as slave to follow the master's current. Losless sensing is used to maintain high efficiency in heavy load situations while maintaing the current sharing error to less than 5% at more than 15A load. The board features an output voltage of 3.3V and can be powered from 5.5V to 26V.

    The MIC45212 Current Sharing Ref. Design board features:
    - maximum output current: 28A
    - output voltage: 3.3V
    - imput voltage: 5.5V to 26V
    - current sharing error: <5% for Iout>15A
    - imput filter for decreasing imput current ripple
