Infineon TDA48632GXUMA2

间歇导电（DCM）

Overview

The TDA4863-2G is a Power-factor Controller IC controls a boost converter in a way that sinusoidal current is taken from the single phase line supply and stabilized DC voltage is available at the output. This active harmonic filter limits the harmonic currents resulting from the capacitor pulsed charge currents during rectification. The power factor which decibels the ratio between active and apparent power is almost one. Line voltage fluctuations can be compensated very efficiently. It contains a wide bandwidth voltage amplifier used in a feedback loop, an overvoltage regulator, an one quadrant multiplier with a wide linear operating range, a current sense comparator, a zero current detector, a PWM and logic circuitry, a totem pole MOSFET driver, an internal trimmed voltage reference, a restart timer and an undervoltage lockout circuitry.
