• Typical Application with Temporary High-Power Circuit Using TDA 16847-2 Controller for Switch Mode Power Supplies. The TDA 16846-2 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)
