ST has released 50W GaN power converter designed for high energy efficiency consumption and industrial power supply

     Stmicroelectronics has announced the VIPerGaN50, the company's first power converter using gallium nitride (GaN) transistors. The Vipergan50 simplifies single-switch flyback power converter designs of up to 50W, enabling higher levels of power efficiency and miniaturization by integrating a 650V GaN power transistor.

     VIPerGaN50 adopts single switch topology, integrates many functions, including built-in current sampling and protection circuits, and adopts low-cost 5mm x 6mm compact packaging. The GaN transistor integrated in the chip can be applied to high switching frequency, thus reducing the volume and weight of the flyback converter. Using this product to design an advanced high efficiency switching power supply (SMPS) can significantly reduce the number of peripheral components.

     VIPerGaN50 can help designers use GaN's third generation semiconductor technology to meet increasingly stringent ecological design specifications and achieve energy conservation and zero carbon emissions globally. Target applications include consumer and industrial power supplies, such as power adapters, USB-PD chargers, and power supplies for household appliances, air conditioners, LED lighting devices, and smart meters.
