Efficient Power Conversion (EPC) has begun mass production of its new 100 V integrated gallium nitride (GaN) power-stage IC family, which includes models EPC23108, EPC23109, EPC23110, and EPC23111. Tailored for high-performance motion-control applications, these ePower™ Stage ICs feature integrated high-side and low-side eGaN® FETs, gate drivers, and level-shifting circuitry, all packaged into compact, thermally enhanced QFN packages. They are capable of operating up to 100 V, with current ratings varying between 35 A and 20 A depending on the model. This integrated design aims to boost power density and efficiency while simplifying system design.
The new IC family boasts features such as fast fault shutdown, safe gate control during power-loss conditions, and the ability to operate continuously at a 100% duty cycle. Additionally, single-input PWM options are available, making them suitable for multi-axis motor-control applications. To complement these ICs, EPC is also releasing evaluation boards—EPC91128, EPC91129, EPC91130, and EPC91131—designed for three-phase BLDC motor-drive applications. These platforms incorporate the new power-stage ICs along with gate drivers, current and voltage sensing, housekeeping power supplies, temperature monitoring, and protection functions.
Available globally through distribution networks like Digi-Key and Mouser, these devices target a variety of applications including humanoid robots, drones, industrial motor drives, medical equipment, synchronous rectification, and high-density DC-DC converters. Pricing for the EPC23108 and EPC23109 is set at US$3.70 each, while the EPC23110 and EPC23111 are priced at US$2.47 each, based on orders of 3,000 units. The evaluation boards, EPC91128 and EPC91129, are priced at US$640 each, whereas EPC91130 and EPC91131 come in at US$630 each.
In conjunction with the product launch, EPC is publishing a technical white paper available in both English and Chinese. This document will cover the architecture, design considerations, and evaluation platforms for these new integrated GaN power-stage ICs. Founded in 2007, Efficient Power Conversion is a semiconductor company focused on enhancement-mode gallium nitride (eGaN®) power devices and integrated circuits. Their GaN-based power solutions serve a range of applications, including DC-DC converters, lidar, motor drives, robotics, drones, and satellite systems.
