UCC28220QDRQ1 Typical application Circuitry Schematics

The UCC28220QDRQ1 from Texas Instruments is a dual-channel, high-speed, interleaved pulse-width modulation (PWM) controller designed for high-power-density DC-DC converters. This device is typically used in applications such as power supplies, DC-DC converters, and electronic devices requiring high-efficiency power conversion. Here are the key elements you would likely find in a circuit using the UCC28220QDRQ1:

1. Power Supply: This device operates with a power supply voltage in the range of 10V to 16V. A decoupling capacitor is usually used near the power supply pins (VDD) to suppress noise.

2. Voltage Feedback: The output voltage of the power converter is sensed using a resistive voltage divider network, which feeds the error amplifier on the EAOUT pin.

3. Current Sense: The current through the power switches (often MOSFETs) is sensed using a current sense resistor or a transformer. This current sense signal is fed to the CSP and CSN pins for each channel.

4. PWM Outputs: The UCC28220QDRQ1 provides two PWM outputs (OUTA and OUTB), which are typically used to control the two power switches in a dual-phase converter.

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

6. Interleaving Control: The UCC28220QDRQ1 provides interleaved operation of the two channels, which helps reduce input and output ripple current, reducing the size of the input and output filter components.

7. Under-Voltage Lockout (UVLO): The UVLO pin is used to set a threshold voltage below which the device will not operate, protecting the circuit from insufficient supply voltage.

8. Soft-Start and Fault Management: Soft-start control and fault management are handled by the SS/FB pin.

9. Protection Features: The UCC28220QDRQ1 incorporates several protection features, including over-current protection (OCP), under-voltage lockout (UVLO), and over-temperature protection.

Remember, this is a general circuit description. The exact schematic and component values would depend on your specific application requirements. For a detailed guide on designing an application circuit with the UCC28220QDRQ1, refer to its datasheet and application notes provided by Texas Instruments, making sure to follow the manufacturer's design guidelines.
