UCC3882DW-1

Overview

The UCC3882DW-1 is a synchronous buck controller manufactured by Texas Instruments, housed in a 28-pin SOIC package. It operates with an average current mode control architecture and supports switching frequencies up to 700 kHz. The device features a 5-bit DAC for precise output voltage adjustment and includes Intel VID code compatibility. It functions within a supply voltage range of 10.8 V to 15 V, delivering a maximum output drive current of 1.5 A. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Implements average current mode control for high-performance synchronous buck applications
• Integrates a 5-bit digital-to-analog converter (DAC) for programmable output regulation
• Supports Intel VID code interface for processor power management compatibility

Applications

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

Procurement Notes

Verify the specific suffix '-1' against the manufacturer's official documentation to confirm pinout and functional equivalence. Ensure the selected variant matches the required thermal performance and packaging specifications for the target PCB layout. Cross-reference the datasheet revision history to validate feature availability and electrical characteristics prior to final procurement decisions.

Selection Notes

Select this component when designing synchronous buck converters requiring average current mode control and Intel VID interface support. The integrated 5-bit DAC allows for flexible output voltage setting without external resistors. Consider the 700 kHz switching frequency limit and 1.5 A driver capability when sizing external components and ensuring adequate thermal management for the SOIC-28 package.
