Description

The UCC3807 family of high speed, low power Cycle integrated circuits contains all of the control and drive circuitry required for off-line and dc-to-dc fixed frequency current mode switching power supplies with minimal external parts count.
These devices are similar to the UCC3800 family, but with the added feature of a user programmable  maximum duty cycle. Oscillator frequency and maximum duty cycle are programmed with two resistors and a capacitor. The UCC3807 family also features internal full cycle soft start and internal leading edge blanking of the current sense input.
The UCC3807 family offers a variety of package options, temperature range options, and choice of critical voltage levels. The family has UVLO  thresholds and hysteresis levels for off-line and battery powered systems.

Features

  • User Programmable Maximum PWM Duty Cycle
  • 100-A Startup Current
  • Operation to 1 MHz
  • Internal Full Cycle Soft Start
  • Internal Leading Edge Blanking of Current Sense Signal
