TDA4862 Datasheet Power-factor Controller

Manufacturer: Siemens Semiconductor Group (now Infineon)

Overview: Power-Factor Controller (PFC) IC for High Power Factor and Active Harmonic Filter Advanced.

General Description

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 prises 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.

Key Features

  • IC for sinusoidal line-current consumption.
  • Power factor approaching 1.
  • Controls boost converter as an active harmonics filter.
  • Internal start-up with low current consumption.
  • Zero current detector for discontinuous operation mode.
  • High current totem pole gate driver.
  • Trimmed ± 1.4% internal reference.
  • Undervoltage lock-out with hysteresis.
  • Very low start-up current consumption.
  • Pin compatible to world sta.
