DESCRIPTION  
3.3-V Input Operation With Availability of  
12-V Bus Bias  
The UCC27223 is a high-speed synchronous  
buck drivers for today’s high-efficiency,  
lower-output voltage designs. Using Predictive  
Gate Drivet (PGD) control technology, these  
drivers reduce diode conduction and reverse  
recovery losses in the synchronous rectifier  
MOSFET(s).

Automatically Adjusts for Changing  
Operating Conditions  
The UCC27223 includes an enable pin that  
controls the operation of both outputs. A logic  
latch is also included to keep both outputs low until  
the first PWM input pulse comes in. The RDS(on)  
of the SR pull-down sourcing device is also  
minimized for higher frequency operations.

FUNCTIONAL APPLICATION DIAGRAM  
V
IN  
This closed loop feedback system detects  
body-diode conduction, and adjusts deadtime  
delays to minimize the conduction time interval.  
This virtually eliminates body-diode conduction  
while adjusting for temperature, load- dependent  
delays, and for different MOSFETs. Precise gate  
timing at the nanosecond level reduces the  
reverse recovery time of the synchronous rectifier  
MOSFET body-diode, reducing reverse recovery  
losses seen in the main (high-side) MOSFET. The  
lower junction temperature in the low-side  
MOSFET increases product reliability. Since the  
power dissipation is minimized, a higher switching  
frequency can also be used, allowing for smaller  
component sizes.
