[{"type":"text","content":"Strategic integration of high-speed, high-voltage gallium nitride (GaN) and low-voltage silicon system-controller chips enables easy-to-use, high-efficiency, fast-charging power systems\nTORRANCE, Calif., March 20, 2023 (GLOBE NEWSWIRE) -- Navitas Semiconductor (Nasdaq: NVTS), the only pure-play, next-generation power semiconductor company and industry leader in gallium nitride (GaN) power ICs and silicon carbide (SiC) technology, has launched a new family of GaNSense Control ICs that deliver unprecedented levels of performance and integration. GaN is a next-generation semiconductor technology that is a significant upgrade over conventional high-voltage (HV) silicon (Si) power semiconductors, while also reducing the energy and physical space needed to deliver that performance. It runs up to 20x faster and can also enable up to three times more power handling or three times faster charging capability, in half the size and weight. Each of these power systems also require an optimized, high-speed, low-voltage (LV) silicon system controller which Navitas has developed and integrated with its high-performance GaN ICs to create the industry’s first GaNSense control IC technology. The initial range of GaNSense Control features high-frequency quasi-resonant (HFQR) flybacks supporting QR, DCM, CCM and multiple-frequency, hybrid-mode operations, with frequencies up to 225 kHz. The range is provided in a single, surface-mount QFN package (NV695x-series) or as a chip-set (NV9510x + NV61xx) for maximum designer flexibility. On the secondary side, integrated synchronous rectifier (SR) power ICs (NV97xx) achieve maximum efficiency at any load condition compared to conventional rectifiers. Integrated features such as loss-less current sensing, HV start-up, frequency-hopping, low standby power, and wide VDD input voltage deliver small, efficient, cool-running systems with fewer components and no RSENSE hot-spot. An array of integrated protection features including 800 V transient voltage, 2 kV ESD, over-voltage, over-current, and over-temperature protection create a robust power IC and reliable power systems. Initial applications cover 20 – 150 W including smartphone, tablet and laptop chargers, consumer and home appliances, point-of-sale, and auxiliary supplies in high-power data center power and 400 V EV systems.
