Turnkey charger solutions for the consumer electronics market, enabling faster design cycles and roll-out of smaller, lighter and more powerful and efficient chargers.


65W Type-C PD QR Charger Reference Design

This 65W reference design combines small size, low cost, high reliability, and easy to implement all in one design. With very high-power density, this charger design meet the performance and safety requirements required by the industry.

  • Input: 90-265V, ~50/60Hz, 1.7A
  • Output: USB-C 5V3A, 9V3A / 12V3A / 15V3A / 20V3.25A 65W max
  • EMI: CISPR22 Conduction and Radiation Class B
  • Power density with case: 18.5 W/in3

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

250W AC/DC Charger PFC and LLC Reference Design

Topology design takes advantage of a two-stage power conditioning system, including a boost AC/DC PFC stage, and an isolated DC/DC half-bridge LLC stage.

  • Input voltage: 90V-264Vac
  • Output: 19Vdc, 13.2A, 250W
  • Passes EN55023 Class B conducted and radiated EMI
  • Meets IEC 62368-1 touch temperature requirement
