Navitas announces GaNSlim
Navitas Semiconductor has announced GaNSlim, a new generation of integrated GaN power ICs designed to simplify and speed the development of small form factor, high-power-density applications.
GaNSlim is claimed 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 a 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 maximises 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,” says 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.”
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.
