The Microchip MIC2101/02 are constant-frequency, synchronous buck controllers featuring a unique adaptive ON-time control architecture. The MIC2101/02 operates over an input supply range of 4.5V to 38V 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 MIC2101 is Hyper Light Load® architecture so it operates in pulse skipping mode at light load but from medium load to heavy load it operates in fixed frequency CCM mode. The MIC2102 is Hyper Speed Control™ architecture so it operates
