UCC2895MDWREP Typical application Circuitry

UCC2895MDWREP

The UCC2895MDWREP is an advanced phase-shift PWM controller that is part of a series designed for high-efficiency, high-power applications. This device incorporates features like programmable switching frequency, soft-start, and shutdown functions, making it well-suited for complex power conversion tasks, particularly in applications that require careful control of the switching characteristics to optimize efficiency and minimize electromagnetic interference. Here are the key connection points and their functions for integrating the UCC2895MDWREP into a circuit:

1. Power Supply and Grounding: The VCC pin (Pin 16) needs to be connected to a power supply within the specified range for the UCC2895MDWREP, and the ground reference is established through the PGND pin (Pin 15) and GNDA pin (Pin 8).

2. Output Control Pins: The device has four output pins: OUT_A (Pin 14), OUT_B (Pin 11), OUT_C (Pin 10), and OUT_D (Pin 9). These pins are designed to drive the gates of external MOSFETs, controlling the power stages in a phase-shifted manner to reduce switching losses and improve efficiency.

3. Feedback and Voltage Sensing: The VFB pin (Pin 7) is used for voltage feedback to regulate the output voltage. By connecting this pin to a voltage divider network from the output, the UCC2895MDWREP can modulate the duty cycle to maintain a constant output voltage.

4. Current Sensing and Protection: The CS pin (Pin 3) is crucial for current sensing, typically connected to a shunt resistor to monitor the current through the power stage. This input is used for overcurrent protection and can modulate or shut down the PWM to prevent damage.

5. Synchronization and Frequency Setting: The UCC2895MDWREP offers a synchronization feature through the SYNC pin (Pin 2), allowing the internal oscillator to synchronize with an external clock source. Additionally, the RT pin (Pin 1) is used to set the oscillator frequency by connecting a resistor to the ground.

6. Soft-Start and Shutdown: The SS/DISB pin (Pin 6) serves dual functions: it can be used for soft-start control by connecting a capacitor to ground, which determines the soft-start timing. It can also be used for shutdown by pulling this pin below a certain threshold voltage.

By carefully configuring these connections, the UCC2895MDWREP can be effectively integrated into power conversion systems, offering precise control over the phase-shifted PWM to optimize performance and efficiency in applications such as power supplies, DC-DC converters, and other power conversion technologies.
