Programmable Maximum Duty Cycle PWM Controller  
FEATURES  
DESCRIPTION  
The UCC3807 family of high speed, low power 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.  
User Programmable  
Maximum PWM  
Duty Cycle  
100µA Startup Current  
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 cur-  
rent sense input.  
Operation to 1MHz  
Internal Full Cycle  
Soft Start  
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.Thresholds are shown in  
the table below.
