GaN Systems Launches Smallest 100W Charger Ref Design

News

Turnkey reference enables rapid design and rollout of smaller and more powerful and efficient GaN chargers

GaN Systems has announced the release of what it says is the industry's smallest 100W dual USB-C intelligent PD GaN charger.

This turnkey reference design is said to achieve the highest power density of any 100W charger on the market. The charger can balance and appropriately power a variety of plugged-in device power level combinations from a single 100W device, two devices at 65W and 30W, or two 45W or 30W devices.

Additionally, when the power draw is below a certain threshold, the charger shifts to a higher efficiency mode to further maximise performance and reduce energy loss.

Available now through GaN Systems, the charger reference design includes prototypes and documentation (schematics, PCB layout, BOM, and design guideline) to shorten design cycles and speed up product launches.

The 100W charger reference design uses GaN Systems' GS-065-011-1-L transistor. Key features include: high-power density of greater than 16W/in3 with case and foldable prong; dual USB-C ports to support universal USB-C protocols and flexible plug-in end devices; peak efficiency of over > 92.5 percent.

The design exceeds EN55032 Class B with > 6dB margin, meets safety IEC62368-1 touch temperature requirement, and meets IEC61000-3-2 for power line harmonics with Power Factor Correction (PFC) circuit.

“Consumers have spoken, and they want GaN chargers. 65 watts was the start and now everyone wants 100 watts and multiple ports,” says Jim Witham CEO of GaN Systems, “Our design, validated by leading customers, is the highest performance, smartest, and smallest charger design that gets customers' products to market in record time.”
