TEA2376DT/1Y

Overview

The TEA2376DT/1Y is a digital configurable interleaved PFC controller in an SO14 package. It operates in discontinuous conduction mode or quasi-resonant mode with valley switching to optimize efficiency, particularly at light loads. The component supports active bridge rectifiers and enables high power factor and low total harmonic distortion across input voltages of 90 VRMS to 264 VRMS. It facilitates efficient single-output power supply designs with minimal external components.

Feature Summary

• Digital configurable two-phase interleaved PFC controller architecture
• Operates in DCM or QR modes with valley switching for optimized efficiency
• Supports integration with active bridge rectifier topologies
• Enables high power factor and low total harmonic distortion performance

Applications

• HD and U-HD televisions
• Server power supplies
• Desktop and all-in-one computers
• Gaming consoles
• High-power adapters

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the TEA2376 family includes variants in SO10 and SO14 packages. Confirm that the TEA2376DT/1Y designation corresponds to the active status version suitable for new designs, distinguishing it from older AT variants which are not recommended for new applications. Ensure compatibility with the intended control interface requirements.

Selection Notes

Select this controller when designing high-efficiency power supplies requiring digital configurability for interleaved PFC stages. It is suitable for applications demanding excellent light-load efficiency through valley switching operation. Consider its compatibility with active bridge rectifiers like the TEA2209 for complete AC-DC solutions. Evaluate the need for digital tuning capabilities to meet specific regulatory standards for power factor and harmonic distortion.
