TEA1716T/2,518

Overview

The TEA1716T/2,518 is a specialized power management IC integrating a Power Factor Correction (PFC) controller and a Half-Bridge Resonant Converter (HBC). It operates on universal AC mains from 70 V to 276 V. The device supports DCM/QR PFC with valley/zero-voltage switching and LLC resonant HBC up to 500 kHz. It features integrated high-voltage startup, burst mode sensing for EuP lot6 compliance, and comprehensive protection including OCP, OVP, demagnetization detection, and open-loop protection.

Feature Summary

• Integrates PFC and HBC controllers in a single chip for simplified design
• Supports universal AC input voltage range directly from rectified mains
• Enables zero-voltage switching for minimized switching losses
• Includes internal high-voltage startup supply and burst mode sensing

Applications

• LCD television power supplies
• Plasma television power supplies
• High-efficiency power adapters
• Desktop computer power units

Procurement Notes

Verify the specific suffix /2,518 indicates tape and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure ESD handling protocols are followed due to humidity sensitivity classification. Validate pinout compatibility against target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component for designs requiring combined PFC and LLC control within a single package. It is suitable for power ranges between 90 W and 500 W. Consider its capability to meet strict standby power regulations like EuP lot6. Evaluate the need for external components versus the integration benefits it provides for cost reduction.

Part Context

This part belongs to the TEA1716T series of resonant power supply control ICs manufactured by NXP Semiconductors. It utilizes a proprietary high-voltage bipolar CMOS-DMOS process. The device replaces older discrete solutions or separate controller chips by combining critical power conversion functions into one highly integrated unit.

Replacement Considerations

TEA1610T/N6/DG,518 is listed as an obsolete predecessor with TEA1716T/1,518 identified as a similar replacement option.
