Navitas driving Spigen’s ArcStation Pro 45W GaN-based fast charger
Navitas Semiconductor Inc of El Segundo, CA, USA says that smartphone accessory maker Spigen Inc of Irvine, CA, USA has extended its range of ArcStation Pro GaN-based fast chargers, now including what is reckoned to be world’s smallest 45W model for Samsung’s flagship smartphone S21 Ultra.
GaN is reckoned to run up to 100x faster than silicon, and enables up to 3x more power or 3x faster charging in half the size and weight. Founded in 2014, Navitas introduced what it claimed to be the first commercial GaN power ICs, which monolithically integrate GaN power field-effect transistors (FETs) with drive, control and protection circuits, enabling faster charging, higher power density and greater energy savings for mobile, consumer, enterprise, eMobility and new energy markets.
The Samsung S21 Ultra smartphone has a large 5000mAhr battery and uses an advanced version of the universal serial bus (USB) power delivery protocol called ‘programmable power supply’ (PPS). PPS can monitor the phone’s battery status in finer detail and adjust the delivered power more accurately to ensure the fastest – and safest – charging speed.
Measuring only 47mm x 47mm x 27mm (60cc) including folding pins, the Spigen 45W (model PE2015) is said to be the world’s smallest 45W PPS charger, and ~30% smaller and lighter than Samsung’s own 45W model.
“The original GaNFast 20W ArcStation Pro charger for the iPhone 12 was our most successful launch,” says Spigen’s product and marketing manager Sean Lee. “By expanding the ArcStation Pro range with increased power, we can extend that success to the Samsung S21 and S21 Ultra, which can fast-charge using a full 45W. The 40W version has dual USB-C outputs, so you can charge two devices at the same time,” he adds.
“Spigen’s ArcStation Pro delivers the fastest charging rates for the new Samsung S21 range – and is differentiated by superb ‘soft-touch’ industrial design, affordable price points and commitment to quality,” comments Stephen Oliver, Navitas’ VP corporate marketing and investor relations.
