Energy Integrations Introduces Business’s First Automotive-Certified Excessive-Voltage Switcher ICs with 1700 V SiC MOSFET

Expanded InnoSwitch3 household slashes part depend and boosts effectivity in EV and industrial functions

SAN JOSE, Calif., February 01, 2022–(BUSINESS WIRE)–Energy Integrations (Nasdaq: POWI), the chief in high-voltage built-in circuits (ICs) for energy-efficient energy conversion, at present introduced the addition of two new AEC-Q100 certified, 1700-volt rated ICs to its InnoSwitch™3-AQ household. The brand new gadgets are the trade’s first automotive-qualified switching energy provide ICs to include a silicon carbide (SiC) major switching MOSFET. Delivering as much as 70 watts of output energy, the brand new ICs are focused to be used in 600- and 800-volt battery and fuel-cell electrical passenger autos, in addition to electrical buses, vans and a variety of business energy functions.

Extremely built-in InnoSwitch ICs scale back the variety of parts required to implement an influence provide by as a lot as 50 %, saving vital circuit-board area, enhancing system reliability and mitigating part sourcing challenges. Units from the award-winning InnoSwitch household at the moment are accessible with a selection of cost-effective silicon, high-efficiency gallium nitride (GaN) and high-voltage SiC transistors, allowing designers to optimize their energy resolution throughout a broad vary of client, pc, communications, industrial and automotive functions.

Peter Vaughan, director of automotive enterprise growth at Energy Integrations, mentioned: “800-volt batteries have gotten customary for EVs. A number of car methods are related to this highly effective electrical supply, but delicate digital management circuits require just some volts for operation and communication. InnoSwitch gadgets enable the electronics to securely sip from the firehose of power accessible on the primary bus, utilizing minimal board space and with out losing power. Most enjoyable is the chance to dramatically simplify the emergency energy provide for the primary traction inverter, which can be known as upon at a second’s discover to function from any voltage between 30 volts and 1000 volts. Our SiC-based InnoSwitch3-AQ gadgets deal with this huge vary with unbelievable ease.”

Supplied in a compact InSOP™-24D package deal, the brand new ICs use a FluxLink™ suggestions hyperlink, offering strengthened isolation as much as 5000 VRMS for secondary-side management. FluxLink know-how allows direct sensing of the output voltage, offering advantages comparable to correct regulation and intensely quick transient response. The circuit will begin from 30 volts with out exterior circuitry – important for purposeful security. Extra safety options embrace enter under-voltage, output over-voltage and over-current limiting.

The inclusion of synchronous rectification and a quasi-resonant (QR) / CCM flyback controller achieves higher than 90% effectivity, simply assembly the strictest OEM necessities. These new elements eat lower than 15 mW at no-load, which is right for decreasing self-discharge in battery administration methods.

The InnoSwitch3-AQ 1700-volt elements are additionally appropriate for industrial markets, the place the built-in resolution replaces discrete controller-plus-MOSFET designs, saving area, time and price whereas growing reliability in functions comparable to renewables, industrial motor drives, battery storage and metering.
