UCC28950QPWRQ1 Typical application Circuitry Schematics

The UCC28950QPWRQ1 from Texas Instruments is a phase-shifted full-bridge controller for DC-DC converters often used in automotive applications. This component is part of the UCC28950 series, which is specifically designed to manage high-power and high-efficiency power conversion tasks. Here's a broad view of what a circuit using the UCC28950QPWRQ1 might include:

1. Power Supply: This device operates within a power supply voltage range of 10V to 20V. To reduce noise, a decoupling capacitor is usually connected near the VDD and ground pins.

2. Voltage Feedback: The output voltage of the power converter is sensed through a resistive voltage divider network and then fed back to the controller via the EAOUT pin.

3. Current Sense: Current through the power switches is typically sensed with a sense resistor or a current transformer. This current sense signal is fed to the CS1P, CS1N (for primary side) and CS2P, CS2N (for secondary side) pins.

4. PWM Outputs: The UCC28950QPWRQ1 provides two pairs of PWM outputs (HO1 and LO1 for the primary-side switches, and HO2 and LO2 for the secondary-side synchronous rectifiers), which drive the gates of the power switches, usually power MOSFETs or IGBTs.

5. Oscillator and Timing Capacitor: The oscillator frequency is set with an RT resistor and a CT capacitor connected to the RT/CT pin.

6. Phase Shift Control: The phase shift between primary-side switches and secondary-side rectifiers is controlled via the PS pin.

7. Soft-Start and Fault Management: The SS/FB pin handles soft-start control (to prevent inrush current during startup) and fault management.

8. Under-Voltage Lockout (UVLO): A UVLO function is provided to prevent operation under low input voltage conditions. The threshold can be programmed using resistors connected to the UVLO pin.

9. Protection Features: The UCC28950QPWRQ1 includes several protection features such as over-current protection, over-voltage protection, and thermal shutdown.

This is a generalized circuit description, and the exact schematic and component values depend on your specific application requirements. For detailed design information, refer to the UCC28950QPWRQ1 datasheet and application notes from Texas Instruments, ensuring to adhere to the manufacturer's design guidelines.
