description  
The UCC3808 is a family of BiCMOS push-pull, high-speed, low-power, pulse-width modulators. The UCC3808  
contains all of the control and drive circuitry required for off-line or dc-to-dc fixed frequency current-mode switching  
power supplies with minimal external parts count.  
The UCC3808 dual output drive stages are arranged in a push-pull configuration. Both outputs switch at half the  
oscillator frequency using a toggle flip-flop. The dead time between the two outputs is typically 60 ns to 200 ns  
depending on the values of the timing capacitor and resistors, thus limiting each output stage duty cycle to less than  
50%. (continued)
