200W high power, double port fast charging without speed reduction, innoseco gallium nitride demo test

2021-09-06

Multi port PD fast charging has multiple output ports, which can charge mobile phones and notebooks at the same time. It is very popular in the market. However, in the current 100W fast charging, a single interface can output 100W. After connecting other interfaces, the output power will be reduced to 65W or 45W, which will soon affect the fast charging experience.

Aiming at the problem of 100W fast charging and speed reduction, innosecco has launched a 200W gallium nitride 3c2a multi port fast charging reference design with high power density, which supports power blind insertion. When double C-Port output, it can output 100W full power without affecting the fast charging experience. When three C-Ports output at the same time, it is 100W + 45W + 45W, ensuring that one C-Port can output full power, While ensuring the use experience, it can also charge the connected equipment as high as possible.

Innosecco's 200W reference design allows 100W fast charging at any C port when output is single port or double port, which fully meets the demand of high-power fast charging. Port a supports 30W fast charging. The output parameters of multi port output strategy can be customized according to requirements.

By increasing the power of multi port PD fast charging to 200W, the power distribution problem of 100W multi port is directly solved. In exchange for doubling the power output with a small increase in volume. Even if the output power of the charger cannot be fully used, the low power output can also reduce the temperature rise of the charger and improve the use experience.

Innoseco's 200W gallium nitride fast charging reference design meets the small volume and efficient power supply design by using gallium nitride switch and PFC + LLC efficient architecture. It solves the problem that the traditional 100 watt multi port charger can not maintain 100 watt output when connecting two devices. And two hundred watt interfaces output at the same time. Compared with two independent hundred watt chargers, the volume advantage is very obvious.

Using high-efficiency LLC resonant architecture with inn650d260a gallium nitride device to output at a fixed voltage can obtain high conversion efficiency and reduce the heat dissipation demand of the charger. The flexible secondary step-down circuit is used at the output end, which can realize a variety of interfaces and output support of different voltages in the charger to meet the personalized needs of manufacturers.
