TEA1713T

General description

The TEA1713 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.

The efficient operation of the PFC is achieved by implementing functions such as quasi-resonant operation at high power levels and quasi-resonant 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 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 that enables 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.

The topology of a PFC circuit and a resonant converter controlled by the TEA1713 is very flexible, enabling it to be used in a broad range of applications with a wide mains voltage range. Combining PFC and HBC controllers in a single IC makes the TEA1713 ideal for controlling power supplies in LCD and plasma televisions.

Highly efficient and reliable power supplies providing over 100 W can be designed easily using the TEA1713, with a minimum of external components.
