Efficient Power Conversion (EPC) has commenced mass production of its new 100 V integrated gallium nitride (GaN) power-stage IC family, which includes models EPC23108, EPC23109, EPC23110, and EPC23111. These ePower™ Stage ICs are engineered for high-performance motion-control applications and incorporate high-side and low-side eGaN® FETs, gate drivers, and level-shifting circuitry within compact, thermally enhanced QFN packages. The devices are capable of operating up to 100 V with current ratings of either 35 A or 20 A, depending on the model. This integrated design aims to enhance power density and efficiency while simplifying overall system design.
The product line is equipped with notable features such as fast fault shutdown, safe gate control during power-loss conditions, and continuous 100% duty-cycle operation. Additionally, single-input PWM options are available for applications involving multi-axis motor control. To support these new power-stage ICs, EPC has also launched the EPC91128, EPC91129, EPC91130, and EPC91131 three-phase BLDC motor-drive evaluation boards. These platforms, built around the new ICs, include gate drivers, current and voltage sensing, housekeeping power supplies, as well as temperature monitoring and protection functions.
The new devices are accessible through EPC’s global distribution channels, including Digi-Key and Mouser. They target a wide array of applications such as humanoid robots, drones, industrial motor drives, medical equipment, synchronous rectification, and high-density DC-DC converters. Pricing for the EPC23108 and EPC23109 models is set at $3.70 each, while the EPC23110 and EPC23111 are priced at $2.47 each, based on orders of 3,000 units. The evaluation boards, EPC91128 and EPC91129, are priced at $640 each, with the EPC91130 and EPC91131 available for $630 each.
In conjunction with the launch, EPC is releasing a technical white paper, available in both English and Chinese, that details the architecture, design considerations, and evaluation platforms for the new integrated GaN power-stage ICs. Founded in 2007, Efficient Power Conversion is a semiconductor company dedicated to developing enhancement-mode gallium nitride (eGaN®) power devices and integrated circuits. Their GaN-based power solutions are utilized in various applications, including DC-DC converters, lidar, motor drives, robotics, drones, and satellite systems.
