Leveraging the advanced PowiGaN technology, the IC provides precise multi-output regulation and virtually lossless operation. Ideal for automotive chargers, solar inverters, and industrial systems, this IC offers a high-performance, cost-effective alternative to silicon carbide solutions.
Power Integrations has introduced a breakthrough in GaN technology with its new 1700 V InnoMux-2 IC. Designed for single-stage, multi-output power supplies, this new IC leverages the company’s proprietary PowiGaN technology, pushing GaN device capability from the company’s previous record of 1250 V to an unprecedented 1700 V. This enables operation from a 1000 VDC bus, achieving over 90% efficiency and supporting up to 60 W across three regulated outputs.
The key highlights include:
- High-efficiency single-stage power conversion
- Efficiency by up to 10%
- Fewer components required
- Consumes under 50 mW with no load
- Supports up to three independently regulated outputs
- Provides both constant voltage and constant current
- Regulation with less than ±1% for load, line, and cross
The IC is ideal for applications like automotive chargers, solar inverters, three-phase meters, and industrial systems, offering a cost-effective alternative to silicon carbide (SiC) solutions. Each output is regulated with one percent accuracy, which reduces the need for post regulators and boosts system efficiency by roughly 10%.The ICs are priced at $4.90 for 10,000 units. Teh company offers a free reference design, RDR-1053, detailing a 60 W dual-output power supply, available on their website.
Radu Barsan, Power Integrations’ VP of Technology, highlighted the company’s rapid advancements, stating, “We’ve set three world-first voltage benchmarks in less than two years with our 900 V, 1250 V, and now 1700 V GaN ICs. The InnoMux-2 combines this high voltage capability with precise multi-output regulation, our FluxLink digital isolation technology, and zero voltage switching (ZVS) for virtually lossless operation.” Ezgi Dogmus from Yole Group commented, “Power Integrations’ 1700 V GaN switch stands out in the market, potentially expanding GaN adoption with cost benefits over SiC.”
