Resonant Inverter with EPC2104?

Is the EPC2104 an appropriate device for a resonant DC/AC Inverter, operating at 100 kHz?

I assume you mean for a motor driver application? If so, while EPC2104 is a good FET, there are newer, easier-to-assemble (solder) GaN FETs that may be better choices.

EPC has a motor drive reference design using a GaN FET that is in production now (and thus, readily available):

Kit EPC9167 (and its -HC = High Current variation)
Home page: Includes links to schematics, Gerbers, parts list, etc.
Quick Start Guide:
Data sheet for the FET used in this design:
The -HC variation uses parallel FETs to get more current output
If a 100 V FET is needed, EPC2088 (100 V) is pin-compatible with EPC2065 (80 V). If you don’t need as low resistance, EPC2204 (100 V) is similar resistance to the FETs in EPC2104.

Hope this helps!

Thx for info!

This isn’t for a motor.

It’s for a constant voltage resonant power supply.

Max output will be about 5 volts at 25 amps.

Voltage will be regulated with PWM of the square wave oscillator.

Does that change your answer?

Thanks for the clarification! The answer is still roughly the same: 2 of the EPC2088 or EPC2204 FETs are newer-generation, and easier-to-solder vs. the EPC2104 dual FET. If an 80 V rating is OK, then EPC2065 is another GaN FET that may be worth considering.

EPC2104 is a BGA device, with 75 balls at a pitch of 0.4 mm horizontal and 0.45 mm vertical. EPC2088, EPC2204, and EPC2065 are all LGA (solder bar), 6-8 solder bars at 0.5 mm pitch. Should be much easier to solder successfully in a lab environment. EPC2204 (100 V, same R as EPC2104) has only 6 solder bars, 0.5 mm pitch.
