TDA4862 Infineon PFC Controller | PG-DIP-8 | 65kHz, 500V

Product Overview

The TDA4862 is a high-performance Power Factor Correction (PFC) controller IC from Infineon Technologies, designed for active power factor correction in switch-mode power supplies. Housed in a PG-DIP-8 package, this device integrates all necessary functions for a boost-type PFC converter, ensuring high efficiency and low harmonic distortion. It operates at a fixed frequency of 65kHz and features a high-voltage startup cell (500V) for direct connection to the rectified mains.
