TDA4862 Datasheet (Siemens Semiconductor)

TDA4862, Power-Factor Controller

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 harmonics filter in a discontinuous mode (free oscillatin
