LM2737 - N-Channel FET Synchronous Buck Regulator Controller

Download the LM2737 datasheet PDF. This datasheet also covers the LM2727 variant, as both devices belong to the same n-channel fet synchronous buck regulator controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM2727 and LM2737 are high-speed, synchronous, switching regulator controllers.

They are intended to control currents of 0.7A to 20A with up to 95% conversion efficiencies.

The LM2727 employs output over-voltage and under-voltage latchoff.
