DESCRIPTION

· The TEA1713 integrates a Power Factor Corrector (PFC) controller and a Half-Bridge resonant Converter (HBC) controller in a multi-chip IC.
· It drives discrete MOSFETs in an up-converter and a resonant half-bridge configuration.
· Ensures efficient PFC operation with quasi-resonant and valley skipping modes.
· Includes OverCurrent Protection (OCP), OverVoltage Protection (OVP), and demagnetization sensing.
· The HBC module is a high-voltage controller for zero-voltage switching LLC resonant converters.
· Fabricated using a high-voltage Bipolar-CMOS-DMOS process for efficient direct start-up.
· Utilizes a low-voltage Silicon On Insulator (SOI) chip for accurate, high-speed protection and control.

FEATURES

· Combines PFC and HBC controllers in a single IC.
· Supports quasi-resonant operation at high and low power levels.
· Includes multiple protection circuits: OCP, OVP, open-loop protection, capacitive mode protection, and a latched protection input.
· High-voltage level shift circuit for safe operation.
· Flexible topology for a wide range of applications.
· Designed for efficient and reliable power supplies over 100 W with minimal external components.

APPLICATIONS

· Ideal for controlling power supplies in LCD and plasma televisions.
· Suitable for applications requiring efficient and reliable power supplies over 100 W.
· Versatile for use in a broad range of applications with a wide mains voltage range.
