Efficient Power Conversion (EPC) Redefines Power Conversion with the Release of ePower(TM) Stage IC Family of Products

HONG KONG,March 20,2020 -- EPCannounces the introduction of an 80 V,12.5 A power stage integrated circuit designed for 48 V DC-DCconversion used in high-density computing applications and in motor drives for e-mobility.

The EPC2152is a single-chip driver plus eGaN® FET half-bridge power stage using EPC's proprietary GaN IC technology. Input logic interface,level shifting,bootstrap charging and gate drive buffer circuits along with eGaN output FETs configured as a half-bridge are integrated within a monolithic chip. This results in a chip-scale LGA form factor device that measures only 3.9 mm x 2.6 mm x 0.63 mm.

When operated in a 48 V to 12 V buck converter at 1 MHz switching frequency,the EPC2152ePower Stage achieves a peak efficiency above 96% with a solution that is 33% smaller in size on the printed circuit board (PCB) compared to an equivalent multi-chip discrete implementation. The peak efficiency of 96% is substantially better than discrete MOSFET or monolithic MOSFET IC-based Power Stage.

The EPC2152is the first offering in what will be a wide-range family of integrated power stages available in chip scale package (CSP) as well as multi-chip quad flat modules (QFM).Within a year the family will fill out with products capable of operating at high frequency up to 3 to 5 MHz range as well as high current from 15 A to 30 A per power stage.

This family of products makes it easy for designers to take advantage of the significant performance improvements made possible with GaN technology. Integrated devices in a single chip are easier to design,easier to layout,easier to assemble,save space on the PCB,and increase efficiency.

"Discrete power transistors are entering their final chapter. Integrated GaN-on-Silicon offers higher performance in a smaller footprint with significantly reduced engineering required," said Alex Lidow,CEO and co-founder of EPC. "This new family of integrated power stages is the next significant stage in the evolution of GaN power conversion,from integrating discrete devices to more complex solutions that offer in-circuit performance beyond the capabilities of silicon solutions and enhance the ease of design for power systems engineers."

The EPC90120development board is a 80 V maximum device voltage,12.5 A maximum output current,half bridge featuring the EPC2152Integrated ePower™ Stage. This 2" x 2" (50.8 mm x 50.8 mm) board is designed for optimal switching performance and contains all critical components for easy evaluation of the EPC2152Integrated ePower Stage.

The EPC2152 ePower Stage and associated development board EPC90120 are available for immediate delivery from Digi-Key at: http://www.digikey.com/Suppliers/us/Efficient-Power-Conversion.page?lang=en .

EPC is the leader in enhancement mode gallium nitride-based power management devices and integrated circuits that provide even greater space,energy,and cost efficiency. EPC was the first to introduce enhancement-mode gallium-nitride-on-silicon (eGaN) FETs as power MOSFET replacements in applications such as DC-DC converters,wireless power transfer,envelope tracking,RF transmission,power inverters,remote sensing technology (Lidar),and Class-D audio amplifierswith device performance many times greater than the best silicon power MOSFETs.
