Part Name(s) : TEA1716T TEA1716T/2
NXP
NXP Semiconductors.
Description : Resonant Power Supply control IC with PFC

General description
The TEA1716T integrates a Power Factor Corrector (PFC) controller and a controller for a Half-Bridge resonant Converter (HBC) in a multi-chip IC. It provides the drive function for the discrete MOSFET in an up-converter and for the two discrete Power MOSFETs in a resonant half-bridge configuration.
Efficient PFC operation is achieved by implementing functions for Quasi-Resonant (QR) operation at high-Power levels and QR operation with valley skipping at lower Power levels. OverCurrent Protection (OCP), OverVoltage Protection (OVP) and demagnetization sensing ensure safe operation under all conditions.
The HBC module is a high-voltage controller for a zero-voltage switching LLC resonant converter. It contains a high-voltage level shift circuit and several protection circuits including OCP, open-loop protection, capacitive mode protection and a general purpose latched protection input.
The high-voltage chip is fabricated using a proprietary high-voltage Bipolar-CMOS-DMOS Power logic process enabling efficient direct start-up from the rectified universal mains voltage. The low-voltage Silicon-On-Insulator (SOI) chip is used for accurate, high-speed protection functions and control.
TEA1716T controlled PFC circuit and resonant converter are very flexible. It can be used for a broad range of applications over a wide mains voltage range. Combining PFC and HBC Controllers in a single IC makes the TEA1716T ideal for controlling Power supplies in LCD and plasma televisions.
Using the TEA1716T highly efficient and reliable Power supplies providing from 90 W to 500 W can be designed easily using the TEA1716T, with a minimum of external components.
The integrated Burst mode and Power management functionality of TEA1716T enable resonant applications that meet the Energy Using Product Directive (EuP) lot 6 (< 0.5 W in Standby mode).
