Microchip Technology EV66F86A MIC2132 Evaluation Board

Microchip Technology EV66F86A MIC2132 Evaluation Board is used to evaluate the MIC2132 constant on-time, dual-phase synchronous buck controller. The controller features a unique adaptive on-time control architecture with stackable features of up to eight phases. The MIC2132 operates over an input supply range from 8.0V to 75V and can be used to supply up to 50A of output current/phase.
