The two100V power stage ICs are the EPC23104, rated at 15A and the EPC23103, rated at 25A join the EPC23102 (100V, 35A) power stage IC.

All three ICs can withstand a maximum voltage of 100V and integrate a complete GaN half-bridge power stage that includes symmetrical FETs in half bridge configuration, half bridge driver, level shifter, bootstrap charging, and input logic interface.

They are supplied in a thermally enhanced QFN package measuring 3.5 x 5.0mm and which has exposed top for dual side cooling and wettable flanks. Footprint compatibility enables customers to upgrade a design for better performance or lower cost without modification to the board, says EPC, to adapt to changing load requirements.

In DC/DC applications, the devices can operate with high efficiency at high switching frequencies (3MHz maximum) and offer higher performance and smaller solution size for 28 to 60V DC/DC in computing, industrial and USB PD 3.1 applications.

In 32 to 48V BLDC motor drives for e-mobility, robotics, power tools and drones, the IC can operate with small deadtimes (21ns) and at 100kHz to increase the system efficiency due to less motor core losses and vibrations, and to reduce or eliminate the electrolytic capacitors.

"The ePower family of products makes it easy for designers to take advantage of the significant performance improvements made possible with GaN technology," says Alex Lidow, CEO and co-founder of EPC. “Integrated devices are easier to design, easier to layout, easier to assemble, save space on the PCB, and increase efficiency,” he adds. In addition, these devices can reduce the weight or increase precision in BLDC motor drives, higher efficiency 48V input DC/DC converters, higher fidelity Class-D audio systems, and other industrial and consumer applications, says Lidow.

Two development boards, the EPC90151 and EPC90152, are half bridge demo boards featuring the EPC23103 and the EPC23104 ePower Stage ICs, respectively. The boards measure 50.8 x 50.8mm and contain all critical components for easy evaluation.

The EPC23103 and EPC23104, together with the development boards (EPC90151 and EPC90152) are available for immediate delivery from Digi-Key.
