UCC3882PW-1

Overview

The UCC3882PW-1 is a synchronous buck controller from Texas Instruments utilizing average current mode control. It operates with a maximum switching frequency of 700 kHz and features a 5-bit DAC for precise voltage regulation. The device supports Intel VID codes for dynamic output voltage adjustment. It is housed in a 28-pin TSSOP package and is designed for high-performance DC/DC conversion applications requiring fast transient response.

Feature Summary

• Integrates a 5-bit digital-to-analog converter for programmable output voltage settings
• Supports Intel VID code interfaces for system-level voltage management
• Employs average current mode control to ensure stable operation under varying load conditions

Applications

• Server and workstation power distribution networks
• High-density point-of-load (POL) converters
• Telecommunications equipment power supplies

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and thermal characteristics. Ensure the selected variant matches the required operating temperature range and packaging specifications for your design implementation.

Selection Notes

Select this component when designing synchronous buck converters that require precise voltage tracking via Intel VID protocols. The average current mode architecture offers superior line and load regulation compared to voltage mode alternatives, making it suitable for sensitive digital loads.

Part Context

This part belongs to the UCC3882 family of synchronous buck controllers. It shares architectural similarities with other members but is distinguished by its specific interface capabilities and internal reference configurations tailored for multi-phase or single-phase high-current applications.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the UCC3882DWTR-1 or UCC3882PW G4, ensuring package and electrical parameter alignment.
