onsemi AC DC Converters, Offline Switches FSB137HLN

The FSB137HLN is a Green-Mode Fairchild Power Switch (FPS,Ñ¢) designed for offline AC-DC conversion applications. It features mWSaver,Ñ¢ technology, which significantly reduces no-load power consumption to less than 40 mW at 230 V_AC, complying with 2013 ErP standby power regulations. The device integrates a 700 V avalanche-rugged SenseFET and a current-mode pulse width modulator (PWM) in a compact 8-pin Dual In-Line Package (DIP), facilitating efficient auxiliary power designs with improved reliability and reduced system costs. This power switch operates with a linearly decreased switching frequency under light-load conditions and employs advanced protection features, including overload protection, under-voltage lockout, and over-voltage protection. It is suitable for various applications, including auxiliary power supplies for PCs, servers, LCD TVs, and game consoles, as well as general-purpose switched-mode power supplies (SMPS). The operating temperature range is from -40¬8C to +105¬8C, making it versatile for different environments.
