Abstract The TEA1713T includes a Power Factor Correction (PFC) controller as
well as a controller for a Half-Bridge resonant Converter (HBC).
This user manual describes a 90 W resonant switching mode power
supply for a typical notebook adapter design based on the TEA1713T. The
board provides an output of 19.5
V/4.65 A. It operates in normal mode for
medium and high power levels and in burst mode for low power levels.
Burst mode operation provides a reduction of power losses to increase
performance.
The efficiency at high power is well above 90 % and the no load power
consumption is well below 500 mW.
