FEATURES  
DESCRIPTION  
•
Variable Switching Frequency Control  
•
Programmable Minimum Switching Frequency  
With 4% Accuracy (3% accuracy at  
temperature range: -20°C to 105°C)  
The UCC25600 high performance resonant mode  
controller is designed for dc-to-dc applications  
utilizing resonant topologies, especially the LLC half  
bridge resonant converter. This highly integrated  
controller implements frequency modulation control  
and complete system functions in only an 8-pin  
package. Switching to the UCC25600 will greatly  
simplify the system design, layout and improve time  
to market, all at a price point lower than competitive  
16-pin device offerings.

Programmable Maximum Switching Frequency  
Programmable Dead Time for Best Efficiency  
Programmable Soft-Start Time  
Easy ON/OFF Control  
Over-Current Protection  
Over-Temperature Protection  
The internal oscillator supports the switching  
frequencies from 30 kHz to 350 kHz. This high  
accuracy oscillator realizes the minimum switching  
frequency limiting with 4% tolerance, allowing the  
designer to avoid "over design" of the power stage  
and, thus, further reducing overall system cost. The  
programmable dead time enables zero-voltage  
switching with minimum magnetizing current. This will  
maximize system efficiency across a variety of  
applications. The programmable soft-start timer  
maximizes design flexibility demanded by the varied  
requirements of end equipments utilizing a half bridge  
topology. By incorporating 0.4-A source and 0.8-A  
sink driving capability, a low cost, reliable gate driver  
transformer is a real option.  
Bias Voltage UVLO and OVP  
Integrated Gate Driver With 0.4-A Source and  
0.8-A Sink Capability

The UCC25600 delivers complete system protection  
functions including over current, UVLO, bias supply  
OVP and over temperature protection.
