When designing a high-efficiency power supply with output power between 100 W and 250 W, should you go with theactive clamp flyback(ACF) topology or theLLC half-bridge resonantcircuit? Senior Product Marketing Engineer Zeeshan Kabeer breaks it down.

• InnoSwitch4-CZ- Offline ZVS flyback switcher IC with 750 VPowiGaNswitch, active clamp drive, synchronous rectification and FluxLink feedback, pairs withClampZeroactive clamp IC
• HiperLCS-2- Offline LLC switcher IC chipset with 600 V FREDFET, synchronous rectification and FluxLink feedback
• HiperPFS-5- Advanced power factor correction (PFC) controller IC with 750 V PowiGaN switch, optimized for high power factor and high efficiency across the load range
