UCC2808 Datasheet PDF

●The UCC2808D-2 is a low power current-mode BiCMOS Push-pull Pulse Width Modulation (PWM) Controller contains all of the control and drive circuitry required for offline or DC to DC fixed frequency current-mode switching power supplies with 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 60 to 200ns depending on the values of the timing capacitor and resistors, thus limiting each output stage duty cycle to less than 50%.

● Dual output drive stages in push-pull configuration

● Internal soft-start

● On-chip error amplifier with 2MHz Gain bandwidth

● On-chip VDD Clamping

● Output drive stages capable of 500mA Peak

● High-speed

● Low-power

● Green product and no Sb/Br

●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
