Efficient Power Conversion (EPC) is advancing its semiconductor offerings by initiating mass production of its 100 V integrated gallium nitride (GaN) power-stage IC family, which includes the EPC23108, EPC23109, EPC23110, and EPC23111. These innovative ePower™ Stage ICs are designed to enhance high-performance motion-control applications by integrating high-side and low-side eGaN® FETs with gate drivers and level-shifting circuitry. The compact and thermally optimized QFN packages facilitate operation up to 100 V, with current ratings of 35 A and 20 A depending on the specific model, aiming to increase power density and efficiency while streamlining system designs.
The product suite boasts features such as fast fault shutdown and safe gate control during power-loss scenarios, along with continuous 100% duty-cycle operation. Additionally, single-input PWM options cater to multi-axis motor-control applications, broadening their utility. To support these new power-stage ICs, EPC is also offering three-phase BLDC motor-drive evaluation boards: the EPC91128, EPC91129, EPC91130, and EPC91131. These platforms incorporate essential components like gate drivers, current and voltage sensing, housekeeping power supplies, and temperature monitoring and protection functions, providing a comprehensive solution for developers.
Available through a global distribution network that includes Digi-Key and Mouser, these devices are targeted at a range 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 US$3.70 each, whereas the EPC23110 and EPC23111 are available for US$2.47 each, based on orders of 3,000 units. The evaluation boards are priced at US$640 for the EPC91128 and EPC91129, and US$630 for the EPC91130 and EPC91131.
In conjunction with the product release, EPC is providing a technical white paper in both English and Chinese. This document delves into the architecture, design considerations, and evaluation platforms associated with the new integrated GaN power-stage ICs, offering valuable insights for engineers and developers. Founded in 2007, EPC specializes in enhancement-mode gallium nitride (eGaN®) power devices and integrated circuits, focusing on GaN-based solutions that cater to applications like DC-DC converters, lidar, motor drives, robotics, drones, and satellite systems.
