Advanced Voltage Mode Pulse Width Modulator

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.
The devices feature low startup current, allowing for efficient off-line starting, 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 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 occurred. 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.
