semiconductor market

DUBLIN, IRELAND — (PRWeb) Navitas Semiconductor, the industry leader in gallium nitride (GaN) power ICs, announced participation in two high-caliber capital markets advisor conferences:

Oppenheimer 24th Annual Technology, Internet & Communications Conference.

August 9^th, 2021

This virtual conference provides a broad look across the supply chain at existing and emerging technologies, plus offers investors the opportunity to evaluate companies at the forefront of these innovations.

2:55pm EDT: Gene Sheridan, Navitas co-founder and CEO presents on the $13.1B opportunity for GaN power ICs and the estimated 117% GaN revenue CAGR to 2026, followed by Q&A. For Oppenheimer clients to participate, and to arrange 1-on-1 meetings, please contact Meghan Connor at meghan.connor@opco.com.

Canaccord Genuity 41st Annual Growth Conference

This virtual conference highlights “Electrification: Why this is a term you need to deeply understand in all portfolios.”

2:00pm EDT: Dan Kinzer, Navitas co-founder and COO / CTO discusses the technology, market and environmental roadmap for next-generation gallium nitride in a panel discussion led by Jed Dorsheimer, Global Head Sustainability, Research at Canaccord Genuity. For live-stream link, and to arrange 1-on-1 meetings, please contact your Canaccord Genuity representative.

Gallium nitride (GaN) is a next-generation semiconductor technology that runs up to 20x faster than legacy silicon chips. Navitas’ proprietary GaN power ICs integrate GaN power (FET) and GaN drive plus control and protection in a single SMT package. These GaNFast™ power ICs become easy-to-use, high-speed, high-performance ‘digital-in, power-out’ building blocks and deliver up to 3x faster charging in half the size and weight, and with up to 40% energy savings compared with earlier silicon solutions.

“With over 140 customer GaN chargers in production, and over 130 patents issued and pending, we believe have created a multi-year, highly-protected lead for Navitas,” noted Sheridan. “We’re off to a great start, and ready to tap into a $13 billion GaN electrification opportunity that goes far beyond chargers and adapters, and into data centers, renewable with a focus on solar, plus electric vehicle and the broader e-mobility segments.”

Navitas has already shipped over 24M GaNFast power ICs to tier-1 companies including Dell, Lenovo, Xiaomi, LG, OPPO and more. Navitas estimates that each GaN power IC shipped saves 4 kg of CO₂ emissions, and that GaN can impact up to 2.6 Gtons of CO₂ reduction annually by 2050.
