EPC Adds Development Boards for Hard-Switching Applications above 10MHz

Efficient Power Conversion Corporation (EPC) introduces a family of development boards, the EPC9022 through EPC9030, to simplify evaluation of the groundbreaking EPC8000 family of ultra-high frequency eGaN power transistors. The EPC8000 family of high frequency eGaN FETs has switching transition speeds in the sub-nanosecond range, making them capable of hard-switching applications above 10 MHz – blurring the line between power and RF transistors. Even beyond the 10 MHz for which they were designed, these products exhibit very good small signal RF performance with high gain well into the low GHz range, making them a competitive choice for RF applications. They are targeted for applications, such as wireless power and 65 V and 100 V devices for envelope tracking, where extremely fast power transistor switching is required.

Products in the EPC8000 family are available with on-resistance values from 125 mΩ through 530 mΩ, and three blocking voltage capabilities, 40 V, 65 V and 100 V. To simplify the evaluation of this family of high frequency, high performance eGaN FETs, EPC is offering a development board for each device in this new product family. The development boards are 2" x 1.5" and contain two eGaN FETs in a half-bridge configuration with minimum switching frequency of 500 kHz. The boards contain all critical components and layout for optimal high frequency switching performance. There are various probe points to facilitate simple waveform measurement and efficiency calculation.

The new development boards include: EPC9024 (for the EPC8004, rated 40V and 7.5A peak with an RDSon of 125mΩ); EPC9027 (for the EPC8007, rated for 40V and 6A peak with an RDSon of 260mΩ); EPC9028 (for the EPC8008, rated for 40V and 2.9A peak with an RDSon of 325mΩ); EPC9029(for the EPC8009, rated for 65V and 7.5A peak with an RDSon of 138mΩ); EPC9025 (for the EPC8005, rated for 65V and 3.8A peak with an RDSon of 275mΩ); EPC9022 (for the EPC8002, rated for 65V and 2A peak with an RDSon of 530mΩ); EPC9030 (for the EPC8010 rated for 100V and 7.5A peak with an RDSon of 160mΩ); and the EPC9023 (for the EPC8003, rated for 100V and 4A peak with an RDSon of 300mΩ).

Evaluation units of the EPC8000 family of devices are immediately available in 2- and 10-piece packs starting at $23 here. EPC9022 through EPC9030 development boards are priced at $150 each and are available for immediate delivery here.
