MIC26603 Datasheet | Micrel Semiconductor

28V, 6A Hyper Light Load™ Synchronous DC/DC Buck Regulator Super Switcher IIG™ General Description Features The Micrel MIC26603 is a constant-frequency, synchronous DC/DC buck regulator featuring adaptive ontime control architecture. The MIC26603 operates over a supply range of 4.5V to 28V. It has an internal linear regulator which provides a regulated 5V to power the internal control circuitry. MIC26603 operates at a constant 600k Hz switching frequency in continuous-conduction mode and can be used to provide up to 6A of output current. The output voltage is adjustable down to 0.8V. Micrel’s Hyper Light 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 MIC26603 offers a full suite of protection Features to ensure protection...
