  • Product Introduction

In high-speed UCC3813-0/-1/-2/-3/-4/-5 homes, low-power integrated circuits contain all the control and driver components required for offline and DC-to-DC fixing frequency current-mode switching of the fewest number of power supplies.

These devices feature the same pin configuration as the UC3842/3/4/5 series, and also offer internal full-cycle soft-start and internally leading current-sense input blanking value-added capabilities.

The UCC3813-0/-1/-2/-3/-4/-5 series offers a choice of packages, temperature range options, maximum duty cycle, and a selection of key various voltage levels. Such as UCC3813-3 and UCC3813-5 are best suited for battery-powered systems that will go down to benchmark parts, while higher reference and UCC3813-2 have high UVLO hysteresis and UCC3813-4 make up for the use of thsese in offline power supplies.

characteristic
 
  • Typical starting power supply current of 100μA
  • Typical operating current is 500μA
  • Operates up to 1MHz
  • Internal soft start
  • Internal soft start failure
  • Built-in current sense signal with cutting-edge blanking
  • 1 amp totem pole output
  • The typical response of the 70NS ball valve ranges from current detection to gate drive output
  • 1.5% tolerance voltage reference
  • The same pins are UCC3802, UC3842, and UC3842A
