Product Summary
The TDA4862G is a power-factor controller (PFC) IC for high power factor and active harmonic filter. The TDA4862G 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 TDA4862G controls a boost converter as an active harmonics filter in a discontinuous mode (free oscillating triangular shaped current mode). The TDA4862G comprises an internal start-up timer, a high gain voltage amplifier, an one quadrant multiplier for approaching unity power factor, a zero current detector, PWM and logic circuitry, and totem pole MOSFET gate driver.
