DESCRIPTION  
ꢀ
ꢀ
12-V or 5-V Input Operation  
The UCC27221 and UCC27222 are high-speed  
synchronous buck drivers for today’s  
high-efficiency, lower-output voltage designs.  
Using Predictive Gate Driveꢁ (PGD) control  
technology, these drivers reduce diode  
conduction and reverse recovery losses in the  
3.3-V Input Operation With Availability of  
12-V Bus Bias

MOSFET(s).  
The  
UCC27221 has an inverted PWM input while the  
UCC27222 has a non-inverting PWM input.  
ꢀ
ꢀ
Automatically Adjusts for Changing  
Operating Conditions  
Predictive Gate Driveꢁ technology uses control  
loops which are stabilized internally and are  
therefore transparent to the user. These loops use  
no external components, so no additional design  
is needed to take advantage of the higher  
efficiency of these drivers.  
Thermally Enhanced 14-Pin PowerPAD  
HTSSOP Package Minimizes Board Area and  
Junction Temperature Rise  
FUNCTIONAL APPLICATION DIAGRAM  
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.
