Description

The UCC2813PW-4G4 from Texas Instruments is a highly integrated, low-power Pulse Width Modulation (PWM) controller designed for a wide range of power supply applications. This device is part of the UCC2813-x family of BiCMOS current-mode PWM controllers that offer improved performance and lower external parts count when used in designing power supply systems.

Key Features

  • Operating Range: The UCC2813PW-4G4 operates with a supply voltage range from 8.5V to 18V, making it versatile for various applications.
  • Current Mode Control: This feature provides inherent line feed-forward, cycle-by-cycle current limiting and ease of loop compensation.
  • Low Startup and Operating Current: The device is designed to consume minimal power with a startup current of typically 0.5µA and an operating current of typically 2.3mA, enhancing the efficiency of the power supply.
  • High-Frequency Operation: With the ability to operate up to 1MHz, the UCC2813PW-4G4 allows for smaller size external components, resulting in compact power supply designs.
  • Trimmed Oscillator Discharge Current: This feature helps in achieving a consistent and precise dead time over the full temperature range.
  • Automatic Feed-Forward Compensation: It helps in maintaining stable operation under varying input voltage conditions.

Applications

The UCC2813PW-4G4 PWM controller is suitable for a diverse set of applications, including:

  • Off-line power supplies
  • DC-DC converters
  • Telecommunication power supplies
  • Industrial power systems
  • Portable electronics

Package and Quality

The device is offered in a 14-pin TSSOP (Thin Shrink Small Outline Package) that is designed for space-constrained applications. The UCC2813PW-4G4 is characterized for operation from -40°C to +85°C, ensuring reliable performance in a wide range of environments.

With its advanced features and robust design, the UCC2813PW-4G4 from Texas Instruments is an excellent choice for designers looking for a high-performance, low-power solution for their power supply needs.
