Microchip Technology EV71S00A MIC21LV32 Evaluation Board
Microchip Technology EV71S00A MIC21LV32 Evaluation Board facilitates an extensive evaluation of the features and performance of the MIC21LV32 capabilities. The MIC21LV32 is a constant on-time, dual-phase synchronous buck controller featuring a unique adaptive on-time control architecture with stackable features up to eight phases.
The Microchip EV71S00A MIC21LV32 Evaluation Board is based on a buck topology and provides an adjustable output voltage between 0.6V and 28V, with a maximum current of 80A when supplied with 4.5V to 36V input voltage. Nevertheless, the board is tuned and optimized for 12V input (±20%) and 0.82V/80A output.
