It provides the drive function for the discrete MOSFET in an up-converter and for the two discrete power MOSFETs ina 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 ization sensing ensure safe operation under all conditions. The HBC module isa isa 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 ofa PFC circuit and a resonant converter controlled by the TEA1713 is very flexible, enabling it to be used ina broad range of applications with a wide mains voltage range. Combining PFC and HBC controllers ina single IC makes the TEA1713 ideal for controlling power supplies in LCD and plasma televisions. Highly efficient and reliable power supplies providing over 100
