Microchip Current Sharing Reference Design Current Sharing for MIC45212 for MIC45212 Current Sharing

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. Lossless 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
input voltage: 5.5V to 26V
current sharing error: <5% for Iout>15A
input filter for decreasing input current ripple
