5A Synchronou s MOSFET Driver General Description The LM27222 is a dual N-channel MOSFET dri ver designed to drive MOSFETs in push-p ull configurations as typically used in synchronous buck regulators.
The LM272 22 takes the PWM output from a controll er and provides the proper timing and d rive levels to the power stage MOSFETs.
Adaptive shoot-through protection prev ents damaging and efficiency reducing s hoot-through currents, thus ensuring a robust design capable of being used wit h nearly any M .
