Efficiency

To support the ever-increasing energy and fast charging needs of mobile devices, designers today are challenged to deliver increasing amounts of power in a travel adapter while also keeping it cool to the touch and maintaining the small size consumers have come to expect. High efficiency, or reducing power loss, is key to achieving the power density without overheating the adapter’s case. For example, delivering 30W today without increasing the volume beyond the 2.4 cu-inch adapter that delivered only 15W a few years ago requires a minimum of 93.2% efficiency to ensure that the case stays under the desired limit of 50 degrees Celsius when operating at room temperature.

"With its ease-of-use and many other benefits for the power supply designer, we anticipate the SZ1101 will be a disruptive force in the industry.— Zahid Rahim, Vice President of Marketing, Silanna Semiconductor.
