Features & Applications

The MIC261203YJL TR is a constant-frequency, synchronous DC/DC buck regulator featuring adaptive on-time control architecture. The MIC261203 operates over a supply range of 4.5 V to 28 V. It has an internal linear regulator which provides a regulated 5 V 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 12 A of output current. The output voltage is adjustable down to 0.8 V.

Micrel’s HyperLight Load® architecture provides the same high-efficiency and ultra-fast transient response as the Hyper Speed Control ä architecture under medium to heavy loads, but also maintains high efficiency under light load conditions by transitioning to variable frequency, discontinuous mode operation.

The MIC261203 offers a full suite of protection features to ensure protection of the IC during fault conditions. These include undervoltage lockout to ensure proper operation under power-sag conditions, thermal shutdown, internal soft start to reduce the inrush current, foldback current-limit and "hiccup" mode short-circuit protection. The MIC261203 includes a Power Good (PG) output to allow simple sequencing.
