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

Expanded InnoSwitch3 household slashes part rely 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, right this moment introduced the addition of two new AEC-Q100 certified, 1700-volt rated ICs to its InnoSwitch™3-AQ household. The brand new units are the business’s first automotive-qualified switching energy provide ICs to include a silicon carbide (SiC) main 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 automobiles, in addition to electrical buses, vehicles and a variety of business energy functions.

Extremely built-in InnoSwitch ICs scale back the variety of elements required to implement an influence provide by as a lot as 50 %, saving important circuit-board area, enhancing system reliability and mitigating part sourcing challenges. Gadgets from the award-winning InnoSwitch household are actually out there with a alternative 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 shopper, laptop, communications, industrial and automotive functions.

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

Supplied in a compact InSOP™-24D package deal, the brand new ICs use a FluxLink™ suggestions hyperlink, offering bolstered isolation as much as 5000 VRMS for secondary-side management. FluxLink know-how permits direct sensing of the output voltage, offering advantages similar 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 larger than 90% effectivity, simply assembly the strictest OEM necessities. These new elements devour lower than 15 mW at no-load, which is good for lowering self-discharge in battery administration techniques.

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 value whereas rising reliability in functions similar to renewables, industrial motor drives, battery storage and metering.

Availability & Assets

A reference design, DER-913Q, and {hardware} package RDK-919Q, can be found for designers wishing to guage the InnoSwitch3-AQ 1700-volt IC. Gadgets are priced at $5.64 for half quantity INN3947CQ-TL and $9.02 for half quantity INN3949CQ-TL in 1,000-unit portions.
