UCC28950TPWRQ1

DC DC Switching Controllers Overview

The UCC28950TPWRQ1 is an automotive-grade, green phase-shifted full-bridge controller with synchronous rectification from Texas Instruments. It operates within a supply voltage range of 8V to 17V and supports switching frequencies up to 1MHz. The device features programmable delays for wide-load zero-voltage switching (ZVS), dynamic SR on/off control for discontinuous conduction mode, and burst mode for light-load efficiency. It includes cycle-by-cycle current limit protection with hiccup mode, UVLO, and thermal shutdown.

DC DC Switching Controllers Feature Summary

• Enhanced wide-range resonant zero-voltage switching capability
• Direct synchronous rectifier control with dynamic on/off management
• Light-load efficiency management including burst mode operation
• Programmable adaptive delay for primary-side ZVS extension

DC DC Switching Controllers Applications

• Electric vehicle power systems
• High-density server power architectures
• Industrial power supplies

DC DC Switching Controllers Procurement Notes

Verify the Q1 suffix indicates AEC-Q100 automotive qualification. Confirm the TPWR package designation matches the required TSSOP-24 form factor. Ensure the design complies with automotive reliability standards. Cross-reference the specific tape-and-reel quantity if applicable. Validate that the component meets the intended environmental operating temperature range.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring high efficiency across wide load ranges. It is suitable for designs needing active synchronous rectification control. Consider it when ZVS must be maintained at light loads. It supports both average and peak current mode control schemes. Verify compatibility with the target input voltage and frequency requirements.
