On the Computex 2018, the innergie Delta released a USB PD charger, built-in A new generation of power devices GaN (GaN).
GaN (GaN) has lower loss and higher switching frequency than traditional silicon-based semiconductors, so this charger is smaller than traditional power chargers.
This is also the first GaN (gallium nitride) 60W USB PD charger available on the market.
First, the appearance of the charger
The innergie Delta's charger comes in a white box. The front side creates a design that looks directly into the approximate appearance of the charger.
On the back of the box, a picture of the appearance of the charger is printed. Innergie Delta is a leader in power management and thermal management solutions. It is a world-class leader in a number of product areas. Using the power supply design and management foundation, integrating global resources and innovative R&D, has been cultivating power and components for years. Energy management, smart green life in three major areas. In Taiwan, China, the United States, Thailand, Japan, Singapore, Mexico, India, Brazil and Europe and other places have R & D centers and production bases.
The side of the box is compatible with the type of device, the charger has multiple voltage output stalls, so it can be compatible with many types of device fast charge.
There is an instruction manual inside the box and a USB-C to USB-C charging cable is included.
The charger adopts a long strip design, AC pin foldable storage.
The pin part of the charger is designed for American regulations and is compatible with domestic standards.
Single USB-C port output, with the word 'PD' printed above the output port.
Positive 'innergie' brand logo.
Detailed parameter information is printed on the back. innergie 60W USB-C portable charger supports 100-240V 50/60Hz 1.5A input, 5V/3A, 9V/3A, 12V/3A, 15V/3A, 20V/3A output, with UL certification, six-level energy efficiency symbol.
The Delta 60W USB PD Charger volume is only one-third of the Apple 61W USB PD Charger.
Compared with the common charger size, from left to right is music as 24W, one plus 20W, Delta 60W, three chargers with little difference in size.
GaN (gallium nitride) has superior breakdown capability, higher electron density and electron mobility than conventional silicon-based semiconductors, and higher operating temperatures. This is the first indication of low loss and high Switching frequency, low loss can reduce the heat generated by the conduction resistance, high switching frequency can reduce the size of transformers and capacitors, help reduce the size and weight of the charger. At the same time, GaN has a smaller Qg and can be easily Raise the frequency and reduce the driving loss.
Second, charger testing
Using the ChargerLAB POWER-Z KT001 test, Delta's charger supports the USB PD2.0 fast charge protocol with five voltage outputs of 5V, 9V, 12V, 15V and 20V. The maximum output power is 60W, which is consistent with the nominal parameters.
In addition, the charger also supports the Apple 2.4A charging protocol, which can be used to charge iPhones and iPads that do not support USB PD fast charging.
Used to charge Huawei mate 9 with power up to 17W. Support USB PD fast charge.
Charge iPhone X, power about 13.6W, support USB PD fast charge.
Recharge the MacBook Pro, power up to 50W, USB PD fast charging. Most laptops with USB PD charging protocol can be adapted.
Charge Nintendo Switch, peak power up to 12W, USB PD fast charge.
Purple rice No. 10 mobile power rush band, power 41W, support USB PD fast charge.
Charge the iPad Air with power up to 11.5W, at full charge.
to sum up
Thanks to the use of next-generation power devices GaN (GaN), the innergie Delta's 60W USB PD charger can be said to be very compact, with a volume that is only half that of current power products. This is also the world's first mass production 60W mini USB PD charger.
The combination of GaN (GaN) technology and USB PD fast charging will greatly improve the performance of the charger and optimize the user experience. It is of great significance to the development of the USB PD fast charging industry.
It is believed that as the technology matures, the subsequent charging devices using GaN technology will be more and more, and the volume of high-power chargers will also be improved.
