UCC2808AQDR-1Q1 Typical application Circuitry

UCC2808AQDR-1Q1

The UCC2808AQDR-1Q1 is a low-power, high-speed, dual-output, advanced current mode pulse-width-modulator (PWM) from Texas Instruments. It's designed for offline and DC-to-DC converter applications with up to 0.5A sourcing or sinking output current.

Here is a general description of an application circuit:

1. Power Supply: The UCC2808AQDR-1Q1 operates on a supply voltage typically of 12V, connected to the VDD pin. Decoupling capacitors are commonly positioned close to the supply pin to reduce noise.

2. Output Transistors: The OUT and OUT pins drive the gate of power Moses, which switches the input voltage to the transformer. These transistors should be chosen based on your specific power requirements.

3. Current Sensing: A resistor is used to sense the current flowing through the output transistors, providing voltage feedback to the ISN Spin.

4. Voltage Feedback: The voltage at the output of the power converter is fed back to the COMP pin through a voltage divider. An optocoupler is often used to isolate the feedback loop.

5. Voltage Reference and Error Amplifier: The UCC2808AQDR-1Q1 has an internal voltage reference and error amplifier. The REF pin is wired with the reference voltage. The EAO UT pin is the output of the error amplifier.

6. Oscillator Timing: A resistor and capacitor are connected to the RT/CT pin to set the oscillator frequency.

7. Soft-Start: An optional capacitor can be connected to the SS pin to set the soft-start time.

8. Under Voltage Lockout: UV LO thresholds are set internally in the UCC2808AQDR-1Q1, but external circuitry can be added for more specific requirements.

This is just a simple, high-level overview of a typical application circuit for the UCC2808AQDR-1Q1. Designing a power converter circuit involves many detailed considerations that are beyond the scope of this description. Always refer to the UCC2808AQDR-1Q1 datasheet and any other relevant resources provided by Texas Instruments for more specific information on designing your application circuit.
