Infineon ICE2QS03HKLA1 Offline Switching Controller

The ICE2QS03HKLA1 from Infineon Technologies is a high-performance isolated flyback controller designed for AC/DC offline switching applications. This controller IC delivers reliable power management with comprehensive fault protection including current limiting, over-temperature, over-voltage, and open-loop protection.

Key Features:

  • Flyback Topology: Optimized for isolated power supply designs
  • Wide Supply Range: 10.5V to 27V operating voltage with 18V start-up
  • 52kHz Switching Frequency: Efficient power conversion with 50% duty cycle
  • Comprehensive Protection: Current limiting, over-load, over-temperature, over-voltage, and open-loop protection
  • Through-Hole Mounting: Easy integration in 8-DIP (0.300", 7.62mm) package
  • Industrial Temperature Range: -25°C to 125°C (TJ) for demanding applications

Applications:

Ideal for aerospace, automotive, industrial, medical, and telecom power supply designs requiring long lifecycle components with full traceability and RoHS/REACH compliance.

Quality Assurance: As an authorized distributor, we provide full traceability, original manufacturer specifications, and guaranteed RoHS/REACH compliance for all components.
