EPC’s EPC2051 100 V eGaN power transistor has a maximum R_DS(on) of 25 mΩ and a 37 A pulsed output current for high-efficiency power conversion in a tiny 1.1 mm² footprint.

Despite the small footprint, the EPC2051 achieves 97% efficiency at a 4 A output while switching at 500 kHz while operating in a 50 V to 12 V buck converter. In addition, the low cost of the EPC2051 brings the performance of GaN FETs at a price comparable to silicon MOSFETs. Applications benefiting from this performance, small size, and low cost include 48 V input power converters for computing and telecom systems, LiDAR, LED lighting, and Class-D audio.
