Efficient Power Conversion Corp (EPC) of El Segundo, CA, USA, which makes enhancement-mode gallium nitride on silicon (eGaN) power field-effect transistors (FETs) for power management applications, has launched the EPC9065, a development board that can serve as the amplifier stage for AirFuel Alliance Class 4 and Class 5 wireless power transfer applications. The board is a zero voltage switching (ZVS) differential-mode class-D amplifier development board configured at, but not limited to, 6.78MHz (lowest ISM band).
The EPC9065 includes all the critical components, including two screw-mounted heat-sinks for increased power capability. It can be easily connected into an existing system to speed end-product time to market.
The development board features the EPC2007C and the EPC8010, which are 100V-rated enhancement-mode gallium nitride FETs. The EPC2007C is used in the class-D amplifier while the EPC8010 is used as a synchronous bootstrap FET. The amplifier can be set to operate in either differential or single-ended mode and includes the gate drivers, a 6.78MHz oscillator, and a separate heat-sink for each Class-D section.
The EPC9065 is priced at $414.00 each and is available now from distributor Digi-Key Corp. Quick Start Guides, containing set-up procedures, circuit diagram, bill of material and Gerber files for the boards, are provided on-line.
