Product Summary

The TDA16846 is a Controller for Switch Mode Power Supplies Supporting Low Power Standby and Power Factor Correction. The TDA16846 is optimized to control free running or fixed frequency flyback converters with or without Power Factor Correction (Current Pump). To provide low power consumption at light loads, this device reduces the switching frequency continuously with load, towards an adjustable minimum (e. g. 20 kHz in standby mode). Additionally, the start up current is very low. To avoid switching stresses of the power devices, the power transistor is always switched on at minimum voltage. A special circuit is implemented to avoid jitter. The device has several protection functions: VCC over-and undervoltage, mains undervoltage, current limiting and 2 free usable fault comparators.
