LM2724A  
High Speed 3A Synchronous MOSFET Driver  
195µA from the 5V rail. The synchronization operation of the  
bottom MOSFET can be disabled by pulling the SYNC pin to  
ground.  
General Description  
The LM2724A is a dual N-channel MOSFET driver which  
can drive both the top and bottom MOSFETs in a push-pull  
structure simultaneously. The LM2724A takes a logic input  
and splits it into two complimentary signals with a typical  
20ns dead time in between. The built-in cross-conduction  
protection circuitry prevents the top and bottom MOSFETs  
from turning on simultaneously. With a bias voltage of 5V, the  
peak sourcing and sinking current for each driver of the  
LM2724A is about 3A. Input UVLO (Under-Voltage-Lock-  
Out) ensures that all the driver outputs stay low until the  
supply rail exceeds the power-on threshold during system  
power on, or after the supply rail drops below power-on  
threshold by a specified hysteresis during system power  
down. The cross-conduction protection circuitry detects both  
driver outputs and will not turn on a driver until the other  
driver output is low. The top gate voltage needed by the top  
MOSFET is obtained through an external boot-strap struc-  
ture. When not switching, the LM2724A only draws up to
