TEA2376AT/1J

Overview

The TEA2376AT/1J is a digital configurable interleaved power factor correction (PFC) controller from NXP Semiconductors. It operates in discontinuous conduction mode (DCM) or quasi-resonant mode with valley switching to optimize efficiency, particularly at light loads. The device supports a 130 kHz reset frequency and functions within an operating temperature range of -40°C to +150°C. It utilizes an SO-10 package for surface mount installation.

Feature Summary

• Digital configurable architecture enabling flexible design implementation
• Interleaved PFC control optimized for high efficiency across load ranges
• Valley switching operation in DCM or QR modes for reduced losses

Applications

• High-definition television power supplies
• Server power systems
• Desktop and all-in-one computer adapters
• Gaming console power units
• High-power adapter applications

Procurement Notes

Verify the specific suffix '1J' against current manufacturer recommendations, as documentation indicates this variant may be marked 'Not Recommended for New Designs'. Confirm package integrity and moisture sensitivity level prior to assembly. Ensure compatibility with required programming interfaces if dynamic parameter adjustment is needed for the target application.

Selection Notes

Select this component for designs requiring digital flexibility in interleaved PFC topologies. Consider the SO-10 package constraints and thermal management requirements for the specified temperature range. Evaluate whether the 'Not Recommended for New Designs' status impacts long-term supply chain stability compared to active variants like the DT series.

Part Context

This part belongs to the TEA2376 family of GreenChip digital PFC controllers designed for efficient AC-DC conversion. It complements other NXP solutions such as the TEA2209 active bridge rectifier controllers. The family targets modern power supplies needing low standby power and high performance under universal input voltage conditions.
