MIC24056

MIC24056 12V, 12A High-Efficiency Buck Regulator SuperSwitcher II General Description Features The Micrel MIC24056 is a constant-frequency, synchronous DC/DC buck regulator featuring adaptive ontime control architecture. The MIC24056 operates over a supply range of 4.5V to 19V. It has an internal linear regulator which provides a regulated 5V to power the internal control circuitry. MIC24056 operates at a constant 600kHz switching frequency in continuous-conduction mode and can be used to provide up to 12A of output current. The output voltage is adjustable down to 0.8V. Micrel’s HyperLight Load® architecture provides the same high efficiency and ultra-fast transient response as the Hyper Speed Control architecture under medium to heavy loads, but also maintains high efficiency under light load conditions by transitioning to variable frequency, discontinuous mode operation. The MIC24056 offers a full suite of protection features to ensure protection of the IC during fault c...
