TDA4862 - Infineon

TDA4862 Power-Factor Controller (PFC) IC

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 oscillating triangular shaped current mode). The TDA 4862 comprises an.
