Power Integrations Combines Programmability, High Efficiency and Small Form Factor in New Zero-Voltage-Switching Power-Supply ICs

Electronica – Power Integrations (NASDAQ: POWI), the chief in high-voltage built-in circuits (ICs) for energy-efficient energy conversion, immediately introduced the InnoSwitch™4-Pro household of digitally controllable, off-line CV/CC Zero Voltage Switching (ZVS) flyback ICs, which considerably cut back the scale of energy adapters. Incorporating a sturdy PowiGaN gallium-nitride major change and steady-state switching frequency of as much as 140 kHz, the extremely built-in gadgets cut back the part rely and PCB space required for ultra-compact adapters for cellphone, pocket book, pill and multi-port equipment.

“InnoSwitch4-Pro ICs interface seamlessly with Power Integrations’ ClampZero™ family of active clamp ICs to achieve ZVS in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM),” acknowledged Aditya Kulkarni, product advertising supervisor at Power Integrations. “ZVS, mixed with our PowiGaN™ expertise, just about eliminates switching losses. Efficiency exceeds 95 p.c, which allows designers to eradicate the warmth sinks, spreaders and potting supplies usually required for thermal administration.”

Further dimension discount of the adapter will be achieved by means of a MinE-CAP™ gadget in mixture with InnoSwitch4-Pro and ClampZero ICs. Based additionally on PowiGaN expertise, MinE-CAP ICs allow enter capacitance dimension discount of roughly 40 p.c.

Capable of delivering as much as 220 W, InnoSwitch4-Pro ICs mix a 750 V PowiGaN major change, controller, FluxLink™ bolstered isolation suggestions hyperlink for secondary-side management, I²C interface, energetic clamp drive and synchronous rectification in a compact InSOP™-28 bundle. The excessive stage of integration drastically simplifies the event and manufacturing of absolutely programmable, extremely environment friendly energy provides. These programmable flyback ICs in mixture with ClampZero and MinE-CAP companion gadgets allow the ultra-compact and slim type elements extremely desired by each OEM accent and aftermarket USB PD and Universal Fast Charging Specification (UFCS) adapters. UFCS is the brand new customary launched by the China Communications Standards Association.

A singular management algorithm is employed by the InnoSwitch4-Pro ICs to allow ZVS in each DCM and CCM. When paired with the ClampZero IC, the algorithm permits for higher-frequency operation and not using a corresponding drop in effectivity. InnoSwitch4-Pro additionally helps quasi-resonant switching in DCM and CCM when used as a standalone product. DCM-only operation will be chosen to scale back SR FET voltage stress. The new ICs additionally function an optimized command set to scale back I²C visitors.

InnoSwitch4-Pro flyback switcher ICs present distinctive CV/CC accuracy, impartial of exterior parts, and devour lower than 30 mW no-load whereas providing line-sensing and complete safety options. Devices are absolutely protected that includes auto-restart or latching fault response for output overvoltage and undervoltage safety, a number of output undervoltage fault thresholds, latching or hysteretic major over-temperature safety, and output bus change short-circuit safety.

Availability & Resources

Two reference designs, DER-960 (100 W), RDK-942 (65 W), can be found for designers wishing to judge the InnoSwitch4-Pro IC. Devices are priced at $1.85 for 10,000-unit portions.
