LM27222
Part Number LM27222
Manufacturer Texas Instruments
Title 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. Adaptive shootthrough p.
