And GaN Systems GAN transistors are used for the latest 100W charger from Harman.
The InfinityLab InstantCharger is a USB PD3.0 charger using the GS-065-011-1-L from GaN Systems. Harman, a subsidiary of Samsung since 2017, used 90% recycled plastics for the charger which has two USB-A ports plus two USB-C ports. The charger is smart enough to know how to allocate power, depending on which devices are plugged in.
“The ability for GaN-based chargers to power multiple devices means that consumers need fewer chargers and can keep them longer. This has significant sustainability implications when considering the more than 30,000 tonnes of landfills generated by discarded cell phone and laptop chargers each year,” said Jim Witham, CEO of GaN Systems.
“Navitas has worked in close partnership with Anker since 2017. Today, Navitas’ next-generation GaNFast Power ICs with GaNSense technology are used in the latest Anker GaNPrime series replacing slow, inefficient, legacy silicon materials,” said the company. For even higher system reliability autonomous GaNSense goes from detection to protection in 30ns – 6x faster than discrete GaN implementations.
Phihong’s 65W adapter includes two USB-C ports and one USB-A port (2C1A) in a small form factor of 51 x 55.3 x 29 mm. It can charge three devices at one time using a quasi-resonant flyback (QRF) topology.
The Transphorm TP65H300G4LSG is a 240 mOhm, JEDEC-qualified PQFN88 surface mount device with a ±18V gate safety margin. The FET is optimal for lower power applications at 150W or below built on QRF, active-clamp flyback (ACF) or LLC resonant topologies and can pair with off-the-shelf controllers including those with integrated drivers without the need for a negative-bias voltage. This simplifies the power system’s design and eliminates the need for additional peripheral circuits, increasing
“Our SuperGaN platform is built from the ground up with four key tenets in mind: reliability, designability, drivability, and reproducibility. Our 240 mOhm device is no exception,” said Kenny Yim, Vice President of Asia Pacific Sales at Transphorm.
“We enable adapter manufacturers to design small, light and cool running products that can offer the latest in advanced USB charging features. It is that type of innovation that is driving GaN adoption in the global adapter market, positioning us to strengthen our foothold in the market with a high performing solution backed by high volume production capabilities,” he said.
