LM27222 Overview
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. Adaptive shootthrough protection prevents damaging and efficiency reducing shoot-through currents, thus ensuring a robust design capable of...
