UCC2808A-2Q1 描述

The UCC2808A is a family of BiCMOS push-pull, high-speed, low-power, pulse-width modulators. The UCC2808A 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 UCC2808A 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 UCC2808A family offers a variety of package options and choice of undervoltage lockout levels.
