TDA4862GGEGXUMA2

Overview

The TDA4862GGEGXUMA2 is a Power Factor Correction (PFC) controller manufactured by Infineon Technologies. It is designed to achieve a power factor approaching unity and functions as an active harmonic filter for boost converters. The device features an internal start-up circuit with low current consumption, a zero-current detector for discontinuous conduction mode operation, and a high-current totem-pole gate driver. It includes a trimmed ±1.4% internal reference, undervoltage lock-out with hysteresis, and a fast overvoltage regulator. The component utilizes an 8-pin DSO package.

Feature Summary

• Controls boost converter topology to function as an active harmonic filter
