MIC26903 - Synchronous DC-to-DC Buck Regulator

Key Features

  • The Micrel MIC26903 is a constant-frequency, synchronous DC/DC buck regulator featuring adaptive ontime control architecture. The MIC26903 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. MIC26903 operates at a constant 600kHz switching frequency in continuous conduction mode and can be used to provide up to 9A of output current. The output voltage is adjustable down to 0.8V. Micrel’s Hyper Li.
