Some applications in North America, including equipment in the rapidly expanding LED lighting, sensing, and smart building markets, run off of a 277V_AC input voltage, requiring a specialized AC/DC power supply design. To address these applications, the 1W and 2W versions of the PSK family feature an extended input range of 85V to 305V_AC, making them well suited for use in not only general ITE, consumer, and industrial equipment, but in these emerging fields as well.
