Programmable Maximum Duty Cycle PWM Controller  
FEATURES  
DESCRIPTION  
User Programmable Maximum PWM  
Duty Cycle  
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.  
100mA Startup Current  
Operation to 1MHz  
These devices are similar to the UCC3800 family, but with the added fea-  
ture 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.  
Internal Full Cycle Soft Start  
Internal Leading Edge Blanking of  
Current Sense Signal  
1A Totem Pole Output  
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.
