Description

The UCC2803D from Texas Instruments is a low-power, high-performance, current-mode PWM controller that is designed for a wide range of power supply applications. This integrated circuit is part of the UCC28C series, which is well-suited for battery-operated and portable devices due to its low startup and operating current characteristics.

Key Features

  • Low Startup and Operating Current: The UCC2803D stands out with its exceptionally low startup current of 0.5 µA and operating current of 2.5 mA, making it an energy-efficient solution for modern electronics.
  • High-Frequency Operation: With an operational frequency range up to 1 MHz, the UCC2803D allows for smaller passive components, resulting in compact power supply designs.
  • Current-Mode Control: This control method provides inherent line feed-forward, cycle-by-cycle current limiting, and ease of loop compensation.
  • Automatic Feed Forward Compensation: The device offers excellent response to input voltage variations, ensuring stable operation under varying conditions.
  • Pulse-by-Pulse Current Limiting: Enhanced protection is provided by limiting the current in each cycle, preventing damage to the controller during overload conditions.
  • Trimmed Oscillator Discharge Current: This feature ensures precise duty cycle clamping, which is crucial for the reliable operation of the power supply circuit.

Applications

The UCC2803D is versatile and can be used in a variety of applications, including:

  • Offline power supplies
  • DC-DC converters
  • Battery chargers
  • Portable devices
  • Green-mode power supplies

Package and Availability

The Texas Instruments UCC2803D is available in an 8-pin SOIC package, which is suitable for surface-mount technology (SMT). It is designed to meet the rigorous demands of high-performance power supply systems, offering a reliable, efficient, and cost-effective solution for designers.

Note: Always consult the datasheet and manufacturer's resources for comprehensive design guidelines and safety information before integrating the UCC2803D into your power supply design.
