HV Start-Up Resonant LLC+PFC Combo Controller

TEA1713T

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