Taigao technology launches the first 240W gallium nitride USB PD3 on the market 1 multi port fast charging power supply scheme

2022-05-03

Taigao Technology launched a 210W gallium nitride power module scheme with PFC + LLC topology using discrete devices in April. This power module scheme has received tens of thousands of broadcasts on well-known online media websites. Netizens commented fiercely that this kind of small and efficient power products have a certain attraction to the market. The 210W gallium nitride power module scheme uses four tp44200nm sealed gallium nitride switches of the first generation of Taigao technology. On PFC and LLC respectively, two are used for PFC boost and two form LLC half bridge, which can significantly reduce the volume of high-power power supply.

Taigao technology has launched a 240W gallium nitride USB PD3 1 multi port fast charging power supply scheme adopts programmable digital power chip PFC + LLC combo efficient topology, and uses four tp44100sg sealed gallium nitride switches of the second generation of Taigao technology to realize "higher efficiency, higher power, smaller volume and lower heating"

240W gallium nitride USB PD3 1. The multi port fast charging power supply scheme adopts the new generation gallium nitride scheme, and the three dimensions of PCBA are 75.8 * 59.4 * 29.6mm ³, The size is 20% smaller than that of apple 61W single port charger. According to the rated output power of 240W, its power density is as high as 1.8w/cm ³; Taigao technology has realized the first 240W gallium nitride USB PD3 in China 1. The power density in the multi port fast charging power supply scheme exceeds 1.75w/cm ³ Reference design.

The 240W gallium nitride power reference design of Taigao technology uses the programmable digital power chip PFC + LLC combo high-efficiency topology. The output constant voltage is 29.5v. Combined with the secondary step-down circuit, the gallium nitride charger has a configuration of 2c1a with three output ports, among which usb-c1 supports 140W output, usb-c2 supports 100W output, usb-a supports 30W output, and the three ports support fast charging output at the same time, with strong performance. Usb-c1 is developed based on the new standard of USB PD 3.1. It supports 28v5a 140W high-power output and is suitable for full blood fast charging of MacBook Pro 2021. Downward compatible with USB PD 3.0, it also supports various common fast charging protocols on the market. Whether it is new fast charging standard equipment or mainstream equipment in the future, it can take all, and take care of the charging needs of multiple devices.

Taigao technology's 240W gallium nitride power reference design adopts constant voltage 29.5v output and secondary step-down circuit. It supports 2c1a three interface output, and usb-c1 supports USB PD3 USB output of 140w-30w notebook can meet the demand of three ports, fast charging output and two ports at the same time. At the same time, the reference design can also be customized according to customer needs to meet different voltage output and interface requirements.
