700V Integrated Power Switch for 16Watt offline flyback converters, 100kHz, Brown In/Out Protection

Favorite

Overview

The FSB127H is a next-generation, green-mode ON Semiconductor Power Switch (FPS™) incorporating 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 700V SenseFET in a single package, allowing auxiliary power designs with higher standby energy efficiency, reduced size, improved reliability, and lower system cost than previous 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 still meeting IEC61010-1 safety requirement. mWSaver™ Green Mode gradually decreases switching frequency as load decreases to minimize switching losses. A new 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 entire universal line voltage range.
Requiring a minimum number of external components, FSB127H provides a basic platform that is well suited for the cost-effective flyback converter design with low standby power consumption.
