TDA4862
TDA4862 - Brand New Infineon PFC (Power Factor Correction)
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
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, 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.
