Infineon Technologies AG PFC (Power Factor Correction) ICE2PCS03HKLA1

The ICE2PCS03 is a standalone Power Factor Correction (PFC) controller designed for continuous conduction mode (CCM) applications. It operates with a wide input voltage range of 85 to 265 VAC and features direct sensing for input brown-out detection, ensuring reliable operation under varying conditions. The device is optimized for fast startup and provides controllable output power through an external sense resistor. This PFC controller incorporates several protection features, including under-voltage lockout, cycle-by-cycle peak current limiting, output over-voltage protection, and soft overcurrent protection. It has a fixed internal switching frequency of 100 kHz, which is trimmed for precision, and supports both current and voltage loop compensation for enhanced user flexibility. The ICE2PCS03 is packaged in an 8-pin DIP or DSO format, making it suitable for applications requiring minimal external components.
