TEA1716T/2,518 is an AC-DC controller and regulator from NXP Semiconductors, integrating a Power Factor Correction Controller (PFC) and a Half-Bridge Resonant Converter (HBC) in a multi-chip IC. It can drive the discrete MOSFET in the boost converter and two discrete power MOSFETs in the resonant half-bridge. TOPCHIP ELECTRONICS, the authorized distributor of NXP's full range of IC electronic components, provides pin diagrams and specifications for TEA1716T/2,518.
Efficient PFC operation is achieved through quasi-resonant (QR) operation at high power and quasi-resonant operation at low power with valley skipping. Built-in Overcurrent Protection (OCP), Overvoltage Protection (OVP), and demagnetization detection ensure safe operation of the controller under all conditions. The HBC module is a high-voltage controller used in zero-voltage switching LLC resonant converters. It includes a high-voltage level shifter and multiple protection circuits, such as overcurrent protection, open circuit protection, capacitive mode protection, and universal lockout protection input. The high-voltage chip is manufactured using a proprietary high-voltage bipolar CMOS-DMOS power logic process, supporting efficient startup directly from rectified universal mains voltage. Low-voltage Silicon-On-Insulator (SOI) chips are used for precise, high-speed protection functions and control.
