Low Power Current Mode Push-Pull PWM

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%.
The UCC3808 family offers a variety of package temperature range options, and choice of undervoltage lockout levels. The family has UVLO thresholds and hysteresis options for off-line and battery powered systems. Thresholds are shown in the table below.
