The UCCx808-x is a family of BiCMOS push-pull pulse-width modulators that are high-speed and low-power. The UCCx808 contains all of the control and drive circuitry required for offline or DC-to-DC fixed frequency current-mode switching power supplies with a minimal external parts count.
The UCCx808-x 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 60ns to 200ns, depending on the values of the timing capacitor and resistors, thus limiting each output stage duty cycle to less than 50%.
