While the adoption of GaN devices has expanded in recent years due to their superior high-speed switching characteristics, the speed of Control ICs, which are responsible for directing the driving of these devices, has become challenging.
In response, ROHM has further evolved its ultra-high-speed pulse control technology Nano Pulse Control™. It is cultivated for power supply ICs, succeeding in significantly improving the control pulse width from the conventional 9ns to an industry-best 2ns. Leveraging this technology allowed ROHM to establish its ultra-high-speed Control IC technology that maximizes the performance of GaN devices.
When pursuing miniaturization of the power supply circuit, it is necessary to reduce the size of the peripheral components through high-speed switching. Achieving this requires a Control IC that can take advantage of the drive performance of high-speed switching devices such as GaN devices.
To propose solutions that include peripheral components, ROHM established ultra-high-speed Control IC technology optimized for GaN devices utilizing proprietary analog power supply technology Nano Pulse Control™.
ROHM is currently working to commercialize Control ICs utilizing this technology, with plans to start sample shipment of 100V 1ch DC-DC Control IC in the second half of 2023. Using in conjunction with ROHM GaN devices (EcoGaN™ series) is expected to result in significant energy savings and miniaturization in a variety of applications, including base stations, data centers, FA (Factory Automation) equipment, and drones.
Going forward, ROHM will continue to develop products that solve social issues by pursuing greater ease-of-use in applications centered on its strengths in analog technology.
