TEA2017AAT/2Y

Power Supply Controllers, Monitors Overview

The TEA2017AAT/2Y is a digital configurable LLC and PFC combo controller for high-efficiency resonant power supplies. It integrates both LLC and PFC controller functionalities within a low-profile, narrow-body SO16 package. The device utilizes a high-speed configurable hardware state machine to ensure reliable real-time performance. The PFC stage supports DCM/QR, CCM fixed frequency, or multimode operation to optimize efficiency across various loads. This architecture enables the construction of complete resonant power supplies with minimal component count. Configuration settings can be adjusted via software loading during development and secured against unauthorized copying.

Power Supply Controllers, Monitors Feature Summary

• Integrates LLC and PFC controller functions in a single digital configurable IC
• Supports PFC operation in DCM/QR, CCM fixed frequency, and multimode configurations
• Features an LLC low-power mode for high efficiency at light loads
• Includes comprehensive protection mechanisms such as OTP, OCP, OVP, OPP, and CMR

Power Supply Controllers, Monitors Applications

• High-efficiency resonant AC-DC power supplies
• Computing and gaming equipment power adapters
• Television power systems
• Industrial equipment power solutions

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix '2Y' against official NXP documentation to confirm it denotes a standard tape-and-reel packaging variant rather than a functional deviation. Ensure compatibility with the intended programming tools, such as the RINGO GUI, for dynamic parameter configuration. Confirm that the SO16 package dimensions align with the target PCB layout constraints. Cross-reference the ordering part number with the latest product data sheet to validate availability and revision status.

Power Supply Controllers, Monitors Selection Notes

Select the TEA2017AAT/2Y when a combined PFC and LLC solution is required to minimize external component count and simplify design. Choose this model over the TEA2017ABT if multimode PFC operation (DCM/QR/CCM) or CCM fixed frequency is necessary for optimal efficiency. Consider this device for applications requiring digital configurability to adjust protection levels and mode transitions without hardware changes. Evaluate the need for secure configuration locking to protect proprietary control parameters.

Power Supply Controllers, Monitors Part Context

The TEA2017AAT belongs to NXP's GreenChip portfolio, designed for smart and energy-efficient power solutions. It complements secondary side controllers like the TEA2095 to form complete synchronous rectification systems. The device family includes variants such as the TEA2017ABT, which offers limited PFC modes compared to the AAT version. Development is supported by demo boards like the TEA2017DB1580 and dedicated design tools for LLC converters.

Power Supply Controllers, Monitors Replacement Considerations

The TEA2017ABT serves as a related variant but lacks multimode and CCM fixed frequency PFC capabilities. No direct public substitute part numbers are confirmed in the provided documentation.
