TEA2017AAT/3Y

Power Supply Controllers, Monitors Overview

The TEA2017AAT/3Y is a digital configurable LLC and PFC combo controller for high-efficiency resonant power supplies. It integrates both LLC and PFC control functions in an SO16 package. The PFC supports DCM/QR, CCM fixed frequency, or multimode operation to optimize efficiency. Designed for 100W to 1400W applications, it features a hardware state machine architecture for reliable real-time performance. The device includes integrated drivers, level shifters, and protection circuits. It enables low component count designs with excellent light-load efficiency and compliance with energy standards like Energy Star and EuP.

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'Y' against official NXP documentation to confirm tape-and-reel packaging specifications and any unique marking codes. Ensure compatibility with the TEA2017DK1007 development kit if programming is required during design validation. Confirm that the /3 variant meets Intel ATX 3 specification requirements for faster startup behavior compared to previous versions.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring high efficiency across full load ranges and strict EMI constraints. The digital configurability allows optimization of switching frequencies and mode transitions to avoid audible noise. Consider the reduced bill of materials due to integrated X-capacitor discharge and driver circuits. Evaluate thermal performance within the SO16 package for high-power density applications.

Power Supply Controllers, Monitors Part Context

The TEA2017 series represents NXP's advanced solution for AC-DC conversion, combining power factor correction and resonant LLC control. The TEA2017AAT/3 variant specifically enhances driver performance and startup speed to meet modern PC power supply standards. It builds upon the TEA2017AAT foundation with improved reliability and compliance features for demanding consumer electronics markets.

Power Supply Controllers, Monitors Replacement Considerations

The TEA2017AAT/2 is the predecessor variant. The /3 version offers improved drivers and faster startup to comply with Intel ATX 3 specifications. Direct pin-to-pin replacement is possible, but verify that the enhanced startup timing does not conflict with existing system reset requirements.
