GF001H
GF001H is Power Switch manufactured by onsemi.
Description
The GF001H is a next- generation, Green- Mode Power Switch. 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 pensation allows stable peak- current- mode control over a wide range of input voltage.
Requiring a minimum number of external ponents, the GF001H provides a solid platform for cost- effective flyback converter design with low standby power consumption.
