electronica - high speed gate driver for power transistor X-GaN

Mass production of Panasonic’s AN34092B high speed gate driver has started in November 2016, according to the company. The driver is optimised for driving the GaN power transistor X-GaN. The company has also started mass production of two types of X-GaN: the PGA26E07BA and PGA26E19BA.

The AN34092B driver is claimed to help the X-GaN achieve high speed switching performance. It can drive transistors at frequencies of up to 4MHz and integrates the active miller clamp function that prevents malfunction during high speed switching.

X-GaN is said to achieve a 600V breakdown enhancement mode and features high speed switching and low on resistance. According to the company, the combination of X-GaN and high speed gate drivers will contribute to space and energy savings.

X-GaN and dedicated high speed gate drivers are suitable for various applications such as 100W to 5kW power supply units, inverters, data centres, mobile base stations, consumer electronics, audio-visual equipment, industrial and medical devices.
