CoolSET™ System in Package (SiP)

概要

Fully Integrated ZVS primary flyback and secondary SR controller with reinforced isolation based on CT Link technology for high power delivery

CoolSET™ SiP integrates an 800 V P7 CoolMOS™, ZVS primary controller, and secondary SR controller with CT Link technology for isolated communication, in a small SMD footprint for up to 60 W power delivery. The ZVS flyback solution reduces BOM, switching losses, and improves EMI performance while achieving higher than 94% efficiency. With industrial-grade qualification (JEDEC47/20/22), the CoolSET™ SiP  family is ideal as an auxiliary power supply for major home appliances and AI Server applications.

The CoolSET™ SiP ZVS quasi-resonant flyback controller integrates an 800 V CoolMOS™ P7 MOSFET in a compact SMD package:

  • The ICE18xEM variants support auxiliary power supplies (45 W/ 60 W power output at 85–300 VAC) with an LDO enable/disable pin.
  • The ICE184LM variant targets general SMPS applications with 45 W capability.

Infineon’s CoolSET™ SiP family targets SMPS applications requiring high efficiency, compact integration, and robust performance. Key use cases include auxiliary power supplies for:

  • Major home appliances (e.g., washing machines, refrigerators, air conditioners, and heatings),
  • Telecom PSU and AI/data center servers
  • Industrial SMPS
