Gallium Nitride (GaN) FETs have revolutionized the power electronics industry, offering advantages such as smaller size, faster switching, higher efficiency, and lower costs compared to traditional silicon MOSFETs. However, the rapid evolution of GaN technology has sometimes outpaced the development of dedicated GaN-specific gate drivers and controllers. Consequently, circuit designers often turn to generic gate drivers designed for silicon MOSFETs, necessitating careful consideration of various factors to ensure optimal performance.

LLC resonant converters have emerged as the preferred topology for an intermediate 48 V to 12 V conversion due to their high efficiency, high power density and good dynamic response. The outstanding performance resulting from the combination of this topology with GaN transistors has been demonstrated in the past. This article presents how the newest generation of GaN devices, such as those from EPC, continues to push the envelope even further.

GaN devices have gone from initial R&D to mainstream designs over the last 15 years. Unfortunately, there are many misunderstandings left-over from those early-stage bipolar drive circuit developments or dead-end technology branches. One of the most pernicious is the topic of bipolar drive. In actuality, unipolar drives are the best way to drive eGaN^® FETs.
