EPC announces the availability of their enhancement-mode gallium nitride (GaN) devices in wafer form for ease of integration. EPC’s eGaN FETs and ICs are traditionally sold as singular chip-scale devices with solder bars or solder bumps. Chip-scale packaging is a more efficient form of packaging that reduces the resistance, inductance, size, thermal impedance, and cost […]
GaN power devices, Part 2: Application
Part 1 of this FAQ explored the basics of GaN switching transistors at the device and physics level. This part will look at driving and applying GaN devices. Q: What do I need to know to use a GaN device? A: There are three functional blocks associated with power switching: the power-device driver, the power […]
GaN power devices, Part 1: Principles
Power devices based on gallium nitride (GaN) are rapidly becoming a viable, higher-performance alternative to silicon MOSFETs due to their higher efficiency and other favorable attributes. In recent years, discrete power-switching and power-handling devices based on gallium nitride (GaN) material have become practical and available, and these devices are now found in many power supplies […]
