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 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,

CC
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.
