LED power supply enters Gan era!

2021-07-21

With the improvement of LED lighting power, the large volume of traditional LED driver has been unable to meet the slim lamp design, and the traditional inefficient drive, the temperature rise in the narrow space is also a serious problem restricting the application. Gallium nitride with high frequency and high efficiency is applied to LED driving power supply, which makes use of the advantages of high frequency and high efficiency to reduce the volume and heat, and becomes the first choice of high-end lamps.

The charging head network has obtained a 200W drive power supply design of innoseco. This power supply adopts ultra-thin design, with three InGaN switches of innoseco built in, and adopts APFC + LLC architecture, which is efficient and light, meeting the stringent space requirements.

At present, LED lighting has been popularized, and the disadvantages of traditional power supply are gradually revealed with the high requirements, such as large volume and high temperature, which can not meet the harsh requirements of existing high-end lamps. Considering the limitations of the existing LED driver, innoseco has launched a new high-power and small volume GaN LED driver by using Gan devices.

The power supply adopts innoseco's high voltage gallium nitride switch tube, which is used in PFC and LLC switching power supply. The small volume and ultra-thin package effectively reduces the thickness of the power supply, and is easy to dissipate heat, realizing the design of high density and high efficiency LED driving power supply. Innoseco's Gan switch is easy to drive, and can work with a variety of controllers to facilitate practical application.

By using gallium nitride in a large amount of LED driving power supply, the advantages of small volume and high efficiency can be brought to LED lighting. After using gallium nitride in high-power LED power supply, the power loss and heat dissipation demand can be reduced, which makes the energy-efficient LED lighting more green and environmentally friendly.
