Product details

Overview

TEA1713T/N2,518 from NXP Semiconductors is a multi-chip IC integrating a Boundary-Mode PFC controller and an LLC resonant half-bridge controller (HBC) for high-efficiency AC-DC power supplies. It drives discrete MOSFETs in both boost and half-bridge stages, supports universal mains input (70–276 V_AC), delivers >100 W output, and enables quasi-resonant valley switching with adaptive non-overlap timing - used in LCD/Plasma TV main power supplies.

For engineers reviewing the TEA1713T/N2,518 datasheet, TEA1713T/N2,518 pinout, TEA1713T/N2,518 application, or TEA1713T/N2,518 equivalent, key selection considerations include integrated dual-control architecture, 24-pin SO24 package with HV start-up capability, burst-mode efficiency optimization at light load, and coordinated protection across PFC and HBC stages including OCP, OVP, UVP, OTP, and capacitive-mode detection.

Technical Context

The TEA1713T/N2,518 implements two independent yet synchronized control modules: a boundary-conduction-mode PFC controller with on-time regulation and valley-sensing, and an HBC controller featuring high-voltage level shifting, adjustable frequency range (min/max set via CFMIN/RFMAX), and adaptive non-overlap timing to prevent shoot-through. Both controllers share a unified protection timer (RCPROT) and latched shutdown logic.

Its dual-die construction combines a high-voltage Bipolar-CMOS-DMOS process for direct mains-startup (SUPHV input) and a low-voltage Silicon-on-Insulator (SOI) die for precision analog sensing and fast protection response. The IC supports flexible supply sourcing - from internal HV start-up, HBC auxiliary winding, or external DC - with hierarchical undervoltage lockout on SUPIC (17 V/22 V start), SUPREG (10.3 V UVP), and boost voltage (SNSBOOST).
