UCC3882PW

Overview

The UCC3882PW is an average current mode synchronous buck controller manufactured by Texas Instruments. It operates with a maximum switching frequency of 700 kHz and utilizes a 28-pin TSSOP package. The device integrates a 5-bit DAC for precise voltage regulation and supports Intel VID codes for dynamic output adjustment. Designed for high-efficiency power conversion, it features programmable slope compensation and robust protection mechanisms suitable for demanding server and workstation applications.

Feature Summary

• Integrates a 5-bit digital-to-analog converter for fine-tuned voltage control
• Supports Intel VID code interfaces for dynamic system management
• Features programmable slope compensation to ensure stable operation across varying load conditions

Applications

• Server and workstation power supplies
• Graphics processing unit (GPU) voltage regulation modules
• High-density point-of-load conversion systems

Procurement Notes

Verify the specific suffix designation to confirm package type and tape-and-reel configuration. Ensure compatibility with Intel VID protocols if dynamic voltage scaling is required in the target design. Cross-reference the manufacturer's latest datasheet for any pinout revisions or environmental compliance updates prior to finalizing procurement specifications.

Selection Notes

Select this component when average current mode control is preferred for superior transient response and ripple rejection compared to voltage mode controllers. Consider the integrated 5-bit DAC capability if precise output voltage trimming without external resistors is necessary. Evaluate the 700 kHz switching frequency against thermal constraints and electromagnetic interference requirements for the specific application environment.
