These devices are intended to simplify and speed up the development of small form factor, high-power-density applications by offering enhanced levels of integration and thermal performance.
GaNSlim enables smaller system designs 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 10 µA, 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 optimise 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 is intended to maximise 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 500 W.
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,” said Reyn Zhan, Sr. 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. GaNSlim increases our GaN addressable market by enabling lower system costs compared to silicon designs for many applications, targeting applications under 500 W across mobile, consumer and home appliance.”
Devices in the NV614x GaNSlim family are rated at 700 V with RDS(ON) ratings from 120 mΩ to 330 mΩ and are available in versions optimized for both isolated and non-isolated topologies.
GaNSlim devices are supplied with a twenty-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.
