Power Integrations announced an expanded offering of the InnoSwitch 4-CZ family of high-frequency, zero-voltage switching (ZVS) flyback controller ICs. When paired with Power Integrations' ClampZero™ active-clamp IC and, optionally, the recently announced HiperPFS™-5 GaN-based power-factor corrector, the new ICs easily address the latest USB PD 3.1 specification for adapters and chargers up to 220 W.
InnoSwitch4-CZ ICs include a robust 750 V PowiGaN™ primary switch, active clamp drive and synchronous rectification in a compact InSOP™-24D package. Secondary-side sensing – achieved using Power Integrations’ FluxLink™ high-speed communications technology – provides exceptional CV/CC accuracy.
InnoSwitch4-CZ ICs consume less than 30 mW at no-load, including input line voltage monitoring. The ICs feature a comprehensive suite of protection features, including auto-restart or latching fault response for output over- and under-voltage; multiple output under-voltage fault thresholds; and latching or hysteretic primary over-temperature protection.
Availability & Resources
A super compact 130 W, USB PD adaptor reference design (DER-957) is available for designers wishing to evaluate the InnoSwitch4-CZ flyback controller IC and ClampZero active clamp IC chipset. Devices are priced starting at $3.07 for INN4072C-TL and $0.66 for CPZ1061M-TLXXX in 1,000-unit quantities of the chipset.
