ICE1QS01 Description

Short technical summary and product information.

The Infineon ICE1QS01 is an integrated circuit designed to control quasiresonant switch mode power supplies. It is optimized for applications requiring low power standby and power factor correction (PFC).

 

Key features include a standby input power of less than 1W, very low start-up current, and soft-start functionality for noiseless power-up. The device supports standby burst mode and digital frequency reduction in small steps as load decreases, down to a minimum of 20 kHz in standby mode. This digital control prevents jitter, even with periodically pulsed loads.

 

Additional capabilities include over- and undervoltage lockout, switch-off at mains undervoltage, and mains voltage dependent fold-back point correction. The ICE1QS01 also incorporates ringing suppression time control based on the output voltage and a free-usable fault comparator, simplifying design-in.

 

This controller is suitable for various power supply designs where efficiency at light loads and stable standby operation are critical. Its features facilitate the development of compact and energy-efficient power solutions.
