General Description  
The LM2722, part of the LM2726 family, is designed to be  
and power-down operation. The gate drive bias voltage  
used with multi-phase controllers. This part differs from the  
needed by the high side MOSFET is obtained through an  
LM2726 by changing the functionality of the SYNC_EN pin  
external bootstrap. Minimum pulse width is as low as 55ns.  
from a whole chip enable to a low side MOSFET enable. As  
a result, the SYNC_EN pin now provides control between  
Synchronous and Asynchronous operations. Having this

control can be advantageous in portable systems since  
Asynchronous operations can be more efficient at very light  
loads.  
The LM2722 drives both top and bottom MOSFETs in a  
push-pull structure simultaneously. It takes a logic level  
PWM input and splits it into two complimentary signals with  
n Plastic 8-pin SO package

typical 20ns dead time in between. The built-in

cross-conduction protection circuitry prevents the top and  
bottom FETs from turning on simultaneously. The  
cross-conduction protection circuitry detects both the driver  
outputs and will not turn on a driver until the other driver  
output is low. With a bias voltage of 5V, the peak sourcing  
and sinking current for each driver of the LM2722 is typically  
3A. In an SO-8 package, each driver is able to handle 50mA
