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)
