AC DC Converters, Offline Switchers datasheet and documents for UCC28880DR

UCC28880DR

AC DC Converters, Offline Switchers Overview

The UCC28880DR is a high-voltage non-isolated AC/DC converter manufactured by Texas Instruments. It utilizes a buck topology and operates within an input voltage range of 36 V to 450 V. The device delivers up to 4 W of output power with a maximum output current of 225 mA. It functions reliably across an extended temperature range from -40 °C to +125 °C. The component is housed in a SOIC-7 surface-mount package.

AC DC Converters, Offline Switchers Feature Summary

High-voltage integrated switching capability for direct off-line operation
Non-isolated buck architecture for simplified design
Extended industrial temperature rating

AC DC Converters, Offline Switchers Applications

Low-power non-isolated AC/DC conversion
Offline power supplies requiring minimal component count
Industrial control systems operating at high voltages

AC DC Converters, Offline Switchers Procurement Notes

Verify the Not Recommended for New Design (NRND) status before implementation, as this indicates potential obsolescence or lack of future production support. Confirm that the non-isolated nature aligns with safety requirements. Ensure the SOIC-7 package footprint matches the PCB layout. Validate input voltage ranges against specific application needs.

AC DC Converters, Offline Switchers Selection Notes

Select this component for applications requiring a compact, non-isolated solution driven directly from high-voltage AC lines. The fixed buck topology limits flexibility compared to programmable controllers but reduces external component count. Consider thermal management due to the 125 °C maximum junction temperature limit. Evaluate if the 4 W power ceiling meets load requirements.

AC DC Converters, Offline Switchers Part Context

This part belongs to the UCC28880 series of high-voltage AC/DC converters. It shares the SOIC-7 package form factor with related models like the UCC28881DR. The series targets simple offline power applications where isolation is not required, distinguishing it from isolated flyback controllers in the broader portfolio.
