SR2803 Datasheet (UTC) - 3A SYNCHRONOUS BUCK CONTROLLER

SR2803, 3A SYNCHRONOUS BUCK CONTROLLER

LINEAR INTEGRATED CIRCUIT The UTC SR2803 is a synchronous buck regulator.

The device provides 3A of continuous load current over a wide input voltage of 4V~28V.

Current mode control provides fast transient response and cycle by cycle current limit.

Integrates soft start, and shutdown mode.
