Technology

Overview

It’s all about efficiency. In any system, power has to be converted or managed. Whenever conversion happens losses occur. These losses manifest themselves as waste heat, which has to be dissipated and gives rise to excess greenhouse gases. Using gallium nitride, with its much lower on-resistance, superior fast-switching capabilities and zero reverse recovery losses a more efficient conversion can be achieved

GaN Systems’ technology features and benefits

• Higher reliability, no wire bonding – smaller form factor, more mechanically robust

• Very high current devices – combining our Island with our GaNPX packaging technology our devices can realize

100’s of Amperes

• Ultra low thermal losses  - heat sinks & fan can be  eliminated or  reduced to further reduce end-product

form factor, weight & cost

• High power density – Ideal for compact power-hungry devices

• Positive temperature coefficient, limiting current as temperature of device increases – Ideal for high-current

multi-die packaged devices

• No-charge storage, eliminating EMI spikes – Improving efficiency of SMPS

• High switching speed, >100V / nS, can be obtained which  lower switching losses – Improving  efficiency of SMPS

• E-Mode devices can control slew rate by simply controlling the gate resistance, enabling EMI and motor control

applications to be optimized

• On-board Drive Assist™ can eliminate drive inductance enabling GaN transistors to reach extremely high speeds

Island Technology

The island structure is the core GaN Systems IP. It has the dual advantage of a reduction in the size and cost of gallium nitride devices, while transferring substantial current from the on-chip metal to a separate carrier. GaN Systems' goal is the easy adoption of gallium nitride by designers and systems engineers.
