UCC28220QDRQ1

DC DC Switching Controllers Overview

The UCC28220QDRQ1 is an automotive-grade, interleaved dual PWM controller designed for high-power isolated DC-DC converter applications. It utilizes peak current-mode control to drive two phases in parallel, effectively doubling the output capability while reducing input and output ripple currents. The device supports Flyback and Forward topologies with a switching frequency of 2 MHz and a maximum duty cycle of 90%. It operates within a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC-Narrow package. The component is AEC-Q100 qualified for automotive reliability.

DC DC Switching Controllers Feature Summary

• Interleaved dual-phase operation reduces input and output ripple currents for improved efficiency
• Peak current-mode control architecture enables precise regulation and fast transient response
• Automotive qualification ensures compliance with rigorous reliability standards
• Integrated protection features support robust performance in high-power isolated applications

DC DC Switching Controllers Applications

• High-power isolated DC-DC converters requiring 50-A to 100-A output capabilities
• Automotive powertrain and chassis systems demanding high reliability
• On-board charger (OBC) front-end stages
• Isolated auxiliary power supplies in electric vehicles

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'QDRQ1' matches the required automotive grade, tape-and-reel packaging, and temperature rating. Confirm that the design requires interleaved dual-phase control rather than single-channel alternatives. Ensure the Bill of Materials aligns with the 16-pin SOIC-Narrow footprint and pinout specifications provided in the official datasheet.

DC DC Switching Controllers Selection Notes

Select this component when designing isolated converters that require high output current density and reduced ripple through phase interleaving. It is suitable for applications supporting Flyback or Forward topologies where a 2 MHz switching frequency is desired. Consider the 90% maximum duty cycle limit when defining the transformer turns ratio and input voltage range for the specific application requirements.

DC DC Switching Controllers Part Context

This part belongs to the UCC2822x family of interleaved PWM controllers from Texas Instruments. These devices are engineered to simplify the design of high-power isolated converters by managing two phases simultaneously. The QDRQ1 designation indicates it is the automotive-qualified version packaged in a 16-pin SOIC-Narrow format, distinct from non-automotive variants or different package options.
