LM27222 - High-Speed 4.5A Synchronous MOSFET Driver

Description

The LM27222 is a dual N-channel MOSFET driver designed to drive MOSFETs in push-pull configurations as typically used in synchronous buck regulators.

The LM27222 takes the PWM output from a controller and provides the proper timing and drive levels to the power stage MOSFETs.
