Advanced Voltage Mode Pulse Width Modulator  
FEATURES  
DESCRIPTION  
• 700kHz Operation  
The UCC35701/UCC35702 family of pulse width modulators is intended for  
isolated switching power supplies using primary side control. They can be  
used for both off-line applications and DC/DC converter designs such as in  
a distributed power system architecture or as a telecom power source.  
• Integrated Oscillator/ Voltage Feed  
Forward Compensation  
• Accurate Duty Cycle Limit  
• Accurate Volt-second Clamp  
• Optocoupler Interface  
The devices feature low startup current, allowing for efficient off-line start-  
ing, yet have sufficient output drive to switch power MOSFETs in excess of  
500kHz.  
Voltage feed forward compensation is operational over a 5:1 input range  
and provides fast and accurate response to input voltage changes over a  
4:1 range. An accurate volt-second clamp and maximum duty cycle limit  
are also featured.  
• Fault Counting Shutdown  
• Fault Latch off or Automatic Shutdown  
• Soft Stop Optimized for Synchronous  
Rectification  
Fault protection is provided by pulse by pulse current limiting as well as the  
ability to latch off after a programmable number of repetitive faults has oc-  
curred.  
• 1A Peak Gate Drive Output  
• 130µA Start-up Current  
• 750µA Operating Current  
Two UVLO options are offered. UCC35701 family has turn-on and turn-off  
thresholds of 13V/9V and UCC35702 family has thresholds of 9.6V/8.8V.  
The UCC35701/2 and the UCC25701/2 are offered in the 14 pin SOIC (D),  
14 pin PDIP (N) or in 14 pin TSSOP (PW) packages. The UCC15701/2 is  
offered in the 14 pin CDIP (J) package.
