1.2
The TDA 16846-2 (this name is used in the description for all types) 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 in small steps with load, towards an adjustable
minimum (e. g. 20 kHz in standby mode). Additionally, the startup current is very low. To
avoid switching stress on the power devices, the power transistor is always switched on
at minimum voltage. A special circuit is implemented to avoid jitter. The device has
Controller for Switch Mode Power Supplies
Supporting Low Power Standby and Power
Factor Correction
