Description

The UCC3801PW is a sophisticated and feature-rich low-power BiCMOS current-mode pulse-width modulation (PWM) controller designed by Texas Instruments. It is an integral component in the design of efficient and reliable power supplies, DC-DC converters, and other power management applications. The UCC3801PW is part of a family of ICs that includes the UCC3803PW and UCC3805PW, each tailored to different power levels and functionalities.

Key Features

  • Current-Mode Control: This technique provides inherent line feed-forward, cycle-by-cycle current limiting, and ease of loop compensation.
  • Low Startup and Operating Current: The UCC3801PW boasts a startup current of typically 0.5 µA and an operating current of 1.5 mA, making it ideal for low-power applications.
  • Trimmed Oscillator Discharge Current: This feature helps in achieving consistent and accurate timing parameters over the entire range of operating temperatures.
  • Automatic Feed-Forward Compensation: It enhances performance by compensating for varying input voltage without the need for additional components.
  • Pulse-by-Pulse Current Limiting: This protects the controller in the event of an overcurrent condition, enhancing system reliability.
  • 100% Maximum Duty Cycle: A high maximum duty cycle is beneficial for use in boost converters or other applications requiring high duty cycles.
  • Under-Voltage Lockout (UVLO): Both startup and operating UVLO thresholds are programmable, ensuring the controller operates only when the supply voltage is sufficient.

Applications

The versatility of the UCC3801PW makes it suitable for a wide range of applications, including but not limited to:

  • Offline and DC to DC power supplies
  • Telecommunication equipment
  • Industrial systems
  • Portable devices
  • Green-mode power supplies

Package and Quality

The UCC3801PW is available in a 14-pin TSSOP (Thin Shrink Small Outline Package) which offers a compact footprint for space-constrained applications. Texas Instruments ensures high-quality standards, and the product is compliant with RoHS directives, reflecting a commitment to environmental responsibility.
