Overview
application INFO available Advanced Voltage Mode Pulse Width Modulator UCC15701/2 UCC25701/2 UCC35701/2 FEATURES DESCRIPTION 700kHz Operation Integrated Oscillator/ Voltage Feed Forward Compensation Accurate Duty Cycle Limit Accurate Volt-second Clamp Optocoupler Interface Fault Counting Shutdown Fault Latch off or Automatic Shutdown Soft Stop Optimized for Synchronous Rectification 1A Peak Gate Drive Output 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 cha...
