The TEA1716 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 integrated burst mode and power management functionality of TEA1716 enable resonant applications that meet the Energy Using Product Directive (EuP) lot 6 (< 0.5 W in standby mode). Highly efficient and reliable power supplies providing from 90 W to 500 W can be designed easily using the TEA1716, with a minimum of external components.
