Infineon ICE3B0365JXKLA1 - CoolSET™F3 Offline Switcher IC

The ICE3B0365JXKLA1 from Infineon Technologies is a high-performance offline switcher IC featuring CoolMOS™ and CoolSET™F3 technology. This integrated power controller combines a 650V CoolMOS™ MOSFET with a current-mode PWM controller in a compact 8-DIP package, delivering reliable 22W power conversion for mission-critical applications.

Key Features & Benefits

  • Integrated 650V CoolMOS™ MOSFET - Reduces component count and board space while improving efficiency
  • Flyback topology - Proven architecture for isolated power supplies with excellent cost-performance ratio
  • Comprehensive fault protection - Current limiting, overload, over-temperature, over-voltage, and open-loop protection ensure system reliability
  • Wide operating range - 10.3V to 26V supply voltage with 18V startup for flexible design integration
  • Extended temperature range - Rated for -25°C to 130°C (TJ) operation in harsh environments
  • 67kHz switching frequency - Optimized for low EMI and efficient transformer design

Ideal Applications

This offline switcher is engineered for demanding industries requiring long lifecycle availability and proven reliability:

  • Aerospace and avionics power systems
  • Automotive electronics and EV charging infrastructure
  • Industrial automation and control equipment
  • Medical device power supplies
  • Telecommunications infrastructure

Technical Advantages

The CoolSET™F3 architecture integrates soft-start control for reduced inrush current, 75% maximum duty cycle for improved transformer utilization, and isolated output design for safety compliance. The through-hole PG-DIP-8 package ensures robust mechanical connection for high-reliability applications.
