TEA1713T
Resonant power supply control IC with PFC
Rev. 2 — 9 February 2011
Product data sheet
1. 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.
