onsemi PMIC - PMIC - AC DC Converters, Offline Switchers - FSQ0170RNA FSQ0170RNA

The FSQ0170RNA is a Green Mode Fairchild Power Switch (FPS,Ñ¢) designed for high-performance offline switch mode power supplies (SMPS). It features an internal avalanche rugged 700V SenseFET and operates at a fixed frequency of 100kHz. The device consumes only 0.8W at 230V AC with a 0.5W load, utilizing burst-mode operation for efficiency. Key protective features include over-voltage protection (OVP), overload protection (OLP), thermal shutdown (TSD), and under-voltage lockout (UVLO). The FSQ0170RNA also incorporates a built-in soft-start mechanism and pulse-by-pulse current limiting, enhancing reliability and safety in applications. This product is suitable for various applications, including auxiliary power supplies for PCs and servers, as well as adapters for consumer electronics like camcorders and printers. It is packaged in an 8-DIP format, making it compact and easy to integrate into designs. The maximum output power is rated at 14W for adapters and 20W for open frame designs under specified conditions.
