GF001H: Green-Mode Fairchild Power Switch (FPS™)
The GF001H is a next-generation, Green-Mode Fairchild Power Switch (FPS™). 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 energy efficiency, reduced size, improved reliability, and lower system cost than previous solutions.
A new frequency modulation reduces EMI emission and built-in synchronized slope compensation allows stable peak-current-mode control over a wide range of input voltage.
Requiring a minimum number of external components, the GF001H provides a solid platform for cost-effective flyback converter design with low standby power consumption.
