High figures of merit characterize 1,200-V Gen 4 SiC FETs
Qorvo announced a next-generation series of 1200V Silicon Carbide (SiC) Field Effect Transistors (FETs) with industry-leading figures of merit in on-resistance. The new UF4C/SC series of 1200V Gen 4 SiC FETs are ideally suited for mainstream 800V bus architectures in onboard chargers for electric vehicles, industrial battery chargers, industrial power supplies, DC/DC solar inverters, as well as […]
Inside a modern power management IC
PMICs today do a lot more than just regulate voltages. Here’s a look at high-end functions these devices provide. Narasimhan Trichy • Qorvo Superior power management and high efficiency have become essential as electronics have become increasingly smaller and more streamlined. The reduction of power dissipation and consequent heat and thermal issues is critical to […]
Fundamentals of fast chargers for phones and notebook PCs
Overlapping protocols and competing standards have created a confusing landscape for USB chargers. Here are the important differences and similarities of most interest to designers. Masashi Nogawa, Staff Systems Engineer Qorvo The first standard for charging via USB connections allowed power delivery at a 7.5-W maximum. Recently the USB standard jumped up to support 100 […]
Energy efficiency, smart lighting, and the IoT
Sure, smart lighting will save energy, but they’ll also be the backbone of systems that can help minimize mini-catastrophes. CEES LINKS, Qorvo THE IoT (internet of things) INCLUDES a rich offering of energy efficiency benefits. Smart lighting is, of course, one of the most common elements of any IoT energy efficiency discussion. Lighting is a […]
