Overview

This application note describes a 45 W dual output power supply reference design (REF_45W1_ZVS_184EM) utilizing the Infineon ICE184EM CoolSET System in Package (SiP). The converter operates across a universal AC input range (90 V AC to 264 V AC) and provides an isolated 12 V/3.75 A output for system hardware and a non-isolated 15 V/0.15 A output for gate drive circuits. The design employs Zero Voltage Switching (ZVS) and secondary-side synchronous rectification to achieve up to 92% efficiency. The ICE184EM integrates an 800 V power MOSFET, primary and secondary controllers, and reinforced isolated communication within a DSO-27 package. Features include a secondary-controlled primary LDO to reduce component count and standby power, auto-restart protection for all fault conditions, and integrated EMI filtering.

Use Cases

  • Home appliances
  • Motor drives
  • Fans and compressors
  • Server auxiliary power
  • Telecom auxiliary power
  • SMPS
