Introduction

AI Translation

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.

Features

AI Translation
  • 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
  • 130μA Start-up Current
  • 750μA Operating Current
  • 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
