Analog Simulation - MIC261203
The Micrel MIC261203 is a constant-frequency, synchronous DC/DC buck regulator featuring adaptive on-time control architecture. The MIC261203 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. MIC261203 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. 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.
