Navitas launches GaNSlim power ICs for ease-of-use, system cost and energy savings in mobile, consumer and home appliances
Gallium nitride (GaN) power IC and silicon carbide (SiC) technology firm Navitas Semiconductor Corp of Torrance, CA, USA has announced GaNSlim, a new generation of highly integrated GaN power ICs that will further simplify and speed the development of small-form-factor, high-power-density applications by offering the highest level of integration and thermal performance.
GaNSlim is said to enable the simplest, fastest and smallest system design by integrating drive, control and protection, with integrated EMI control and loss-less current sensing, all within a high-thermal-performance proprietary DPAK-4L package. Additionally, with an ultra-low startup current below 10µA, GaNSlim devices are compatible with industry-standard SOT23-6 controllers and eliminate HV startup.
Integrated features such as loss-less current sensing eliminate external current sensing resistors and optimize system efficiency and reliability. Over-temperature protection ensures system robustness and auto sleep-mode increases light and no-load efficiency. Autonomous turn-on/off slew rate control maximizes efficiency and power density while reducing external component count, system cost and EMI.
GaNSlim features a patented 4-pin, high-thermal-performance, low-profile, low-inductance, DPAK package. This package enables 7°C lower temperature operation versus conventional alternatives, supporting high-power-density designs with ratings up to 500W. Target applications include chargers for mobile devices and laptops, TV power supplies, lighting, etc.
“Our GaN focus is on integrated devices that enable high-efficiency, high-performance power conversion with the simplest designs and the shortest possible time-to-market,” says Reyn Zhan, senior manager of technical marketing. “Our new GaNSlim portfolio - built on integration, ease-of-use and low-cost manufacturing methods - continues to grow the customer pipeline, with over 50 new projects already identified,” he adds. “GaNSlim increases our GaN addressable market by enabling lower system costs compared to silicon designs for many applications, targeting applications under 500W across mobile, consumer and home appliance.”
Devices in the NV614x GaNSlim family are rated at 700V with RDS(ON) ratings from 120mΩ to 330mΩ and are available in versions optimized for both isolated and non-isolated topologies.
As with other Navitas GaN ICs, GaNSlim devices are supplied with an industry-leading 20-year warranty, while demo boards for QR flyback, single-stage PFC, boost PFC plus QR flyback and TV power supply designs allow for rapid evaluation and selection of the optimum device for a given application.
