power-factor controller (pfc) ic.
* IC for sinusoidal line-current consumption
* Power factor approaching 1
* Controls boost converter as an active
harmonics filter
* Internal start-up wit.
The timer starts or restarts the TDA 4862 if the drive output has been off for more than 15 µs after the inductor curre.
The TDA 4862 is excellent convenient for designing a preconverter in ballasts and switched mode power supplies with sinusoidal line current consumption and a power factor approaching unity.
The TDA 4862 controls a boost converter as an active harmoni.
