GS-EVM-CHG-100W

100W PFC QR USB PD Charger with 2 Type-C Ports Reference Design

This GaN based 100W charger reference design provides a turn-key solution for the “100W, Multiple-ports” growing demand of consumer electronics industry. It displays outstanding performance, and best-in-class features of ultra-high-power density, high efficiency, and low surface temperature. This reference design is based on GaN Systems GaN transistors GS-065-011-1-L. The combined advantages of these transistors of low gate charge, low parasitic capacitor, and low on-state resistor lead to a more efficient system, demonstrating the benefits of GaN technology and meeting high power density without sacrificing the efficiency and thermal performance.

  • Input: 90-264V, 50/60Hz
  • Output: maximum of 100W, 5V3A / 9V3A / 12V3A / 15V3A / 20V5A
  • Case Dimension: (2.4inch x 2.4incg x 1.1 inch)
  • Flexible and smart power distribution
