CoolSET™ System in Package (SiP)

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

anchor

Overview

CoolSET™ SiP integrates a HV switch, a 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 various applications.

About

The CoolSET™ SiP ZVS quasi-resonant flyback controller integrates an 800 V / 950 V CoolMOS™ P7 MOSFET in a compact SMD package:

• The ZCM Series is capable of voltage zero-crossing detection with X-cap discharge after AC power-off.

• The XM Series offers input X-cap discharge after AC power-off and an enable pin ENS/ENP. 

• The EM Series is characterized by an enable pin ENP/ENS to turn-on/off the primary-side LDO.

• The LM Series products incorporate an ENP pin and targets general and industrial SMPS applications.

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.

Qualified for industrial applications according to the relevant tests of JEDEC47/20/22

• Planned certification according to IEC 60747-17 (VDE 0884-17).

• Planned certification according to UL 1577.

• Planned EN and CQC certification for IEC 62368-1 (safety for audio/video/IT equipment) and GB4943.1-2022.

• Planned certification according to IEC 60355-1 (safety for home appliance equipment).

• Planned certification according to IEC 61010-1 (lab equipment).
