GigaDevice drives digital power in joint lab with Navitas
Navitas Semiconductor is working with Chinese microcontroller designer GigaDevice in a joint lab for digital power supply designs.
The lab will target the use of the Navitas gallium nitride (GaN chips with the GigaDevice microcontrollers in areas such as AI datacentres, consumer power supplies and even electric vehicles.
The move highlights a way to tackle the challenge of designing with GaN chips, which need more complex control algorithms. This has been addressed in part by integrating the gate driver and voltage regulator into the GaNFast chips alongside the power transistor. Providing the chip with a microcontroller further simplifies the design of a power system with higher efficiencies by using the higher switching frequency of the GaN devices.
GigaDevice has automotive qualified microcontrollers and flash memory devices. The GD32 microcontrollers are based on the ARM Coretex-M7 core and are aimed at body control, automotive lighting, smart cockpits, assisted driving and motor power systems where smaller DC-DC converters are needed. This taps into the higher frequency operation that allows smaller magnetic components.
- GigaDevice taps Arteris for next generation chip interconnect
- GreatWall taps Navitas for 2.5kW AI datacentre power supply
- Navitas targets Ruby certification for datacentre power supplies
“Digital power stands as one of GigaDevice’s core strategic markets. MCUs play a pivotal role in advancing the intelligence of digital power systems, enhancing energy efficiency, and ensuring operational security.” said Vincent Li, GigaDevice Senior Vice President, CTO, and General Manager of MCU BU.
“By working with Navitas, we will deeply integrate our MCU with GaNFast technology to develop competitive solutions for industrial automation and new energy vehicles. This collaboration not only technological synergy but also a critical step toward greener, more efficient industry development.”
