Overview

The FSB137HL is a next-generation, Green-Mode, ON Semiconductor Power Switch (FPS™) that incorporates ON Semiconductor’s innovative mWSaver™ technology, which dramatically reduces standby and no-load power consumption, enabling conformance to all worldwide Standby Mode efficiency guidelines. It integrates an advanced current-mode pulse width modulator (PWM) and an avalanche-rugged 700 V SenseFET in a single package, allowing auxiliary power designs with higher standby efficiency, reduced size, improved reliability, and lower system cost than prior solutions.
ON Semiconductor Semiconductor’s mWSaver™ technology offers best-in-class minimum no-load and light-load power consumption. An innovative Ax-CAP® method, one of the five proprietary mWSaver™ technologies, minimizes losses in the EMI filter stage by eliminating the X-cap discharge resistors while meeting IEC61010-1 safety requirements. mWSaver™ Green Mode gradually decreases switching frequency as load decreases to minimize switching losses.
Proprietary asynchronous jitter decreases EMI emission and built-in synchronized slope compensation allows stable peak-current-mode control over a wide range of input voltage. The proprietary internal line compensation ensures constant output power limit over the entire universal line voltage range.
Requiring a minimum number of external components, FSB137HL provides a basic platform that is well suited for the cost-effective flyback converter design with low standby power consumption.
