LM27222 Datasheet High-speed 4.5a Synchronous MOSFET Driver

Manufacturer: Texas Instruments

Overview: LM27222 .ti. SNVS306B – SEPTEMBER 2004 – REVISED MARCH 2013 LM27222 High-Speed 4.

General 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.

Adaptive shootthrough protection prevents damaging and efficiency reducing shoot-through currents, thus ensuring a robust design capable of being used with nearly any MOSFET.
