UCC3882PWTR-1

Overview

The UCC3882PWTR-1 is an average current mode synchronous buck controller manufactured by Texas Instruments. It operates with a maximum switching frequency of 700 kHz and is housed in a 28-pin TSSOP package. The device supports Intel VID code programming for precise voltage regulation. It features a 5-bit DAC for programmable output voltage adjustment, enabling flexible configuration for various power supply applications requiring high efficiency and fast transient response.

Feature Summary

• Implements average current mode control architecture for synchronous buck topologies
• Integrates a 5-bit digital-to-analog converter for programmable voltage settings
• Supports Intel VID code interface for standardized processor power management
• Designed for high-efficiency operation with advanced phase-shift capabilities

Applications

• Intel processor core voltage regulation modules
• High-density point-of-load converters
• Server and workstation power distribution systems
• Telecommunications equipment power supplies

Procurement Notes

Verify the specific suffix TR-1 indicates tape and reel packaging when sourcing. Confirm the 28-pin TSSOP package type matches your PCB footprint requirements. Ensure compatibility with Intel VID protocols if used in processor power stages. Check for RoHS compliance markings on the datasheet to meet environmental standards. Validate that the 700 kHz maximum switching frequency aligns with your thermal and component selection constraints.

Selection Notes

Select this controller for applications requiring precise voltage tracking via Intel VID codes. The integrated 5-bit DAC allows for fine-tuned output voltage adjustments without external resistors. Consider the 28-pin TSSOP package for space-constrained designs needing multiple control pins. Evaluate the 700 kHz switching frequency against inductor size and efficiency targets. Ensure the average current mode control suits your transient response requirements.

Part Context

This component belongs to the UCC3882 family of synchronous buck controllers from Texas Instruments. It is designed for high-performance power delivery networks. The PWTR-1 variant specifically denotes the tape and reel packaging format within the TSSOP-28 package line. It complements other UCC38xx series devices offering similar control architectures.

Replacement Considerations

UCC3882PW: Identical functional specifications but in tube packaging instead of tape and reel. UCC3882PWG4: Same device with lead-free and RoHS-compliant manufacturing process. UCC3882PWTR: Standard tape and reel version without the -1 suffix distinction in some listings.
