Description
FSAR001 is designed to replace capacitor-fed (“cap
dropper”) non-isolated power supplies, offering better
high-power conversion performance and high-energy
efficiency than a cap dropper solution. The appliance
needs no inductor, uses few components, and offers
lower cost.
FSAR001 integrates a 600V high-power device, startup
controller, voltage control circuit, synchronous circuit,
low dropout regulator, over-temperature protector, overvoltage
protector, under-voltage protector, and currentlimit
circuit onto a monolithic IC.
