Resonant AC/DC supplies have superior efficiency at high power output. The TEA1916 is a digital controller simplifying the complexity of resonant LLC designs and providing easy tuning. It succeeds the very popular TEA1716 used in many resonant Switch Mode Power Supplies for e.g. PC's & TV's, but the TEA1916 is actually very suitable for any power supply > 75W, e.g. medical, industrial and server power supplies. The TEA1916 uses a new digital cycle-by-cycle architecture (Vcap control) to enable a new type of operation at low power loads. This increases the efficiency at low output power, using an accurately controlled burst mode operation. The TEA1916 also achieves very low power consumption in standby or off state; a key performance parameter to differentiate from competition. To obtain the highest efficiency the TEA1916 works excellent together with NXP's TEA1995 Synchronous Rectifier.
