Fairchild FSB1x7H mWSaver™
Fairchild Power Switch (FPS™)
The FSB1x7H mWSaver™ Fairchild Power Switch (FPS™) is a next-generation, green-mode Fairchild Power Switch (FPS™) incorporating Fairchild'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 700V SenseFET in a single package, allowing auxillary power designs with higher standby energy efficiency, reduced size, improved reliability, and lower system costs than previous solutions.
