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 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.
Protective features are: input undervoltage lockout with hysteresis, VCC zener clamp, cycle-by-cycle current limiting, output voltage limiting for fast and slow load changes up to open circuit, and a sinking gate driver current activated whenever undervoltage mode occurs.
The output voltage of this preconverter is regulated with high accuracy.
Therefore the device can be used for world-wide line voltages without switches.
The TDA 4862 is the improved version of the TDA 4817 with a pinout equivalent to world standard.
