GaN Efficiency

Need for speed—GaN operates at higher frequencies with up to 4x faster switching to lower crossover losses and increase system efficiency

Feel the power—GaN in a totem-pole configuration lowers component count and EMI filter size to deliver the same power in a smaller footprint

Smaller, lighter, cooler—Higher efficiency and increased power density means lower overall system cost
