Abstract The TEA1716 integrates a power factor corrector 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 upconverter and
for the two discrete power MOSFETs in a resonant half-bridge
configuration.
The TEA1716 provides fully integrated burst mode operation functions for
the PFC and HBC to reduce converter power consumption at low-power
output. In burst mode operation, the power consumption of the IC is also
minimized for further reduction of the power consumption in a standby
state.
The PFC circuit and resonant converter topology controlled using the
TEA1716 is very flexible which enables it to be used in a broad range of
applications across a wide mains voltage range. Combining PFC and HBC
controllers in a single IC makes the TEA1716 ideal for controlling power
supplies in high-power adapter topologies.
Highly efficient and reliable power supplies can be designed with the
TEA1716 using the minimum of external components.
