MIC2103YML 10A EV: 5V @ 10A, 12 ~ 75V in

Summary

The Micrel MIC2103/04 are constant-frequency, synchronous buck controllers featuring a unique adaptive on time control architecture. The MIC2103/04 operates over an input supply range of 4.5 to 75V and can be used to supply up to 15A of output current. The output voltage is adjustable down to 0.8V with a guaranteed accuracy of ±1%. The device operates with programmable switching frequency from 200kHz to 600kHz.

The MIC2103 has Hyper Light Load® architecture, so it can operate in pulse skipping mode at light load. However, from medium load to heavy load, it operates in fixed frequency CCM mode.
