UCC2897ARGPR Typical application Circuitry Schematics

The UCC2897ARGPR from Texas Instruments is an advanced active clamp pulse-width modulation (PWM) controller, designed for use in a variety of power supply designs including isolated DC-DC converters, and forward, flyback and push-pull converters. Here are some of the key elements you would typically find in a circuit using the UCC2897ARGPR:

1. Power Supply: This device operates with a supply voltage between 11V to 16V. A decoupling capacitor is often placed near the VDD pin to filter out any supply noise.

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

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

4. Output Gate Drive: The UCC2897ARGPR provides two gate drive outputs, one for the main switch (OUTA), and one for the active clamp switch (OUTB).

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

6. Soft-Start and Fault Management: A capacitor connected to the SS pin controls the soft-start function, which can help to manage inrush current during startup.

7. Under-Voltage Lockout (UVLO): The UVLO function prevents operation under low input voltage conditions, and the threshold can be programmed using resistors connected to the UVLO pin.

8. Protection Features: The UCC2897ARGPR includes several protection features such as over-current protection, over-voltage protection, and over-temperature protection.

This is a generalized 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 UCC2897ARGPR, refer to its datasheet and any relevant application notes provided by Texas Instruments, ensuring to follow the manufacturer's design guidelines.
