CGPS, or Chip-GaN Power Semiconductor Corp., describes a portfolio of gate drivers, power controllers and integrated power solutions aimed at applications such as AI data centers, drones, motor drives and electric-vehicle power supplies. Its claims about efficiency, safety and integration come from company-authored partner content—not independent testing—and publicly reviewed materials do not establish a specific orderable part or current inventory.
What is CGPS?
Chip-GaN Power Semiconductor Corp. is a Taiwan-based power-management IC design company. Its company profile lists Hsinchu, Taiwan, and a 2021 founding year. CGPS says its portfolio includes gate drivers, primary- and secondary-side controllers, power-management ICs and integrated power solutions.
The article titled “CGPS Pioneers Next-Gen Gate Drivers” was authored by CGPS and published as EE Times partner content on February 13, 2025. Its product advantages and performance statements should therefore be understood as the company’s presentation, not independent validation. EE Times notes that partner content is created by or on behalf of partners and may not represent the views of its editors. Read the EE Times partner article.
What does CGPS mean by an integrated GaN gate driver?
A gate driver controls a power transistor’s switching. CGPS describes an approach that integrates a gate driver with a GaN power device, which it calls GaNevo, while retaining the device’s three-terminal drain, gate and source structure. Professor Ke-Horng Chen, CGPS co-founder and technical advisor, said: “This is not just simple co-packaging.”

CGPS argues that combining the driver and power device can reduce external components and parasitic effects. Those are claimed design benefits; the partner article does not provide an independent comparison, test setup or component-level measurements that quantify them. Designers evaluating the approach would still need a device datasheet and application information to assess switching behavior, ratings, thermal design and protection in a particular circuit.
Which applications and semiconductor materials does CGPS target?
CGPS names AI servers and data centers, drones, motor drives and EV power supplies as intended application areas. The company’s stated focus reflects common power-design concerns such as power density, energy efficiency, switching behavior and heat management; it does not establish deployment in a named production system.

In the EE Times article, Chen presents broad material-selection ranges: silicon for applications below 200 V, GaN for 200–650 V, and SiC for 800–1000 V. These ranges are a high-level framing, not a substitute for selecting a component against a design’s ratings and operating conditions. Topology, switching frequency, thermal design, protection needs and system requirements all affect the choice.

What product details and availability are established?
CGPS describes products based on E-GaN, D-GaN and SiC MOSFET technologies, as well as controllers and integrated power solutions. Its public website provides product and R&D sections, but the accessible catalog information does not establish a readable part number, detailed datasheet, stock status, retail listing or authorized distributor. The company site is the appropriate starting point for current product information: CGPS official website.

How should designers evaluate a gate-driver or power-stage option?
CGPS’s article explains its integration rationale but does not provide a comparative test table or verified component data. To compare an integrated GaN solution with separate silicon, GaN or SiC components, check the following for the specific design:
Rank #4
- Package / Case: PDIP-8
- Number of Drivers: 1 Driver
- Operating Supply Voltage: 4.5 V to 18 V
- Pd - Power Dissipation: 730 mW
- Number of Outputs: 1
- Voltage and topology: Confirm device ratings and suitability for the converter or motor-drive topology.
- Switching and losses: Review switching frequency, loss data and test conditions rather than relying on general efficiency claims.
- Thermal behavior and power density: Check thermal limits and the system-level cooling assumptions.
- Integration and layout: Determine what is integrated, what remains external, and whether layout or parasitic effects are documented.
- Protection: Verify the actual protection features and operating limits in the datasheet.
- Design support and sourcing: Request datasheets, evaluation hardware, current production status and a confirmed supply channel.
How strong are CGPS’s performance and market claims?
Chen warns that high current can create bouncing effects and high-voltage switching can cause coupling that may damage a controller, MOSFET or gate driver. He also describes CGPS’s offering as a broader solution spanning front-end control and power-device protection. These are company statements in the partner article; no independent test-lab results or standards-body assessment are presented there.

It also cites a MarketsandMarkets forecast of a market growing from $142.8 billion in 2024 to $837.8 billion by 2030, with a 34.3% CAGR. That estimate is a secondary attribution reproduced in CGPS’s article; the underlying report was not independently verified in the reviewed sources.
