Product Overview
The LM27222M/NOPB is a 4.5A dual N-channel high-speed Synchronous MOSFET Driver, designed to drive MOSFETs in push-pull configurations as typically used in synchronous buck regulators. The LM27222M/NOPB takes the PWM output from a controller and provides the proper timing and drive levels to the power stage MOSFETs. Adaptive shoot-through protection prevents damaging and efficiency reducing shoot-through currents, thus ensuring a robust design capable of being used with nearly any MOSFET. The adaptive shoot-through protection circuitry also reduces the dead time down to as low as 10ns, ensuring the highest operating efficiency. The peak sourcing and sinking current for each driver of the LM27222M/NOPB is about 3A and 4.5A respectively with a Vgs of 5V. System performance is also enhanced by keeping propagation delays down to 8ns. Efficiency is once again improved at all load currents by supporting synchronous, non-synchronous and diode emulation modes through the LEN pin.
