UCC2808D-2 Typical application Circuitry Schematics

The UCC2808D-2 from Texas Instruments is a low-power, dual-output, current-mode push-pull PWM controller. It is frequently employed in power supply, DC-DC converters, and other applications involving power conversion. What may commonly be present in a circuit employing the UCC2808D-2 is as follows:

1. Power Supply: The device operates with a power supply voltage in the range of 10 V to 15 V. A decoupling capacitor is usually used near the VDD pin to suppress noise and ensure stable operation.

2. Voltage Feedback: The output voltage of the power converter is sensed using a voltage divider network and is fed back to the COMP pin.

3. Current Sense: The current through the power switch (often a MOSFET) is sensed using a current sense resistor or a transformer. This current sense signal is fed to the CS pin.

4. PWM Outputs: The UCC2808D-2 provides two complementary PWM outputs (OUTA and OUTB), which are typically used to control the two switches in a push-pull converter.

5. Oscillator and Timing Capacitor: The oscillator frequency is set by connecting a timing resistor (RT) and timing capacitor (CT) to the RT/CT pin.

6. Soft-Start Capacitor: A soft-start capacitor can be connected to the SS pin to ensure a controlled startup.

7. Under-Voltage Lockout (UVLO): The UVLO threshold voltage is internally set, but an external resistor divider can be connected to the UVLO pin to adjust the UVLO threshold voltage.

8. Protection Features: The UCC2808D-2 includes several protection features, such as over-current protection and under-voltage lockout.

Please be aware that this is a broad description of the circuit. Your particular application needs would determine the precise schematic and component values. For detailed information on how to design an application circuit with this device, you should refer to the UCC2808D-2's datasheet and application notes provided by Texas Instruments, ensuring to follow the manufacturer's design guidelines.
