ICE2QS01FKLA1

Overview

The ICE2QS01FKLA1 is a quasi-resonant PWM controller for power factor correction (PFC) applications, manufactured by Infineon Technologies. It operates in continuous conduction mode (CCM) with a switching frequency of 80 kHz. The device is housed in an 8-DIP package and supports a supply voltage range of 11 V to 25 V. It features a startup current of 450 µA and functions within a temperature range of -40°C to +125°C. This component is designed for efficient power management in AC/DC conversion systems.

Feature Summary

• Integrates quasi-resonant control for enhanced efficiency
• Supports continuous conduction mode operation
• Features low startup current for reduced standby power

Applications

• Power factor correction in AC/DC converters
• High-efficiency power supply designs
• Consumer electronics power management

Procurement Notes

Verify the specific suffix 'FKLA1' against official Infineon documentation to confirm pinout and electrical characteristics, as suffixes can indicate variations in packaging or material compliance. Ensure compatibility with existing PCB footprints and thermal management requirements before integration.

Selection Notes

Select this component for applications requiring CCM PFC control with a fixed 80 kHz switching frequency. Consider its 8-DIP package for through-hole mounting needs and verify that the 11 V to 25 V supply range aligns with the system's bias voltage constraints.

Part Context

This part belongs to Infineon's PFC controller lineup, designed to improve power quality in electronic devices. It complements other PMIC solutions by offering dedicated functionality for power factor correction, ensuring compliance with regulatory standards for harmonic distortion in power supplies.

Replacement Considerations

The ICE2PCS03GXUMA1 is listed as a similar alternative. Verify functional equivalence regarding switching frequency, control mode, and package compatibility before substitution.
