DESCRIPTION  
The UCC25705-Q1 and UCC25706-Q1 devices are 8-pin voltage mode primary side controllers with fast  
over-current protection. These devices are used as core high-speed building blocks in high performance isolated  
and non-isolated power converters.  
UCC25705-Q1/UCC25706-Q1 devices feature a high speed oscillator with integrated feed-forward compensation  
for improved converter performance. A typical current sense to output delay time of 25 ns provides fast response  
to overload conditions. The IC also provides an accurate programmable maximum duty cycle clamp for increased  
protection which can also be disabled for the oscillator to run at maximum possible duty cycle.  
Two UVLO options are offered. The UCC25705-Q1 with lower turn-on voltage is intended for dc-to-dc converters  
while the higher turn-on voltage and the wider UVLO range of the UCC25706-Q1 is better suited for offline  
applications.  
The UCC2570x-Q1 family is offered in an 8-pin SOIC (D) package.
