FSAR001
AC-DC Linear Regulator
Features
ƒ High Output Voltage Accuracy: 2%
ƒ Output Voltage: 5V
ƒ Low Ground Current: < 2.0mA
ƒ Ultra-Fast Line and Load Transient Response
ƒ Hysteretic Thermal and Current-Limit Protections
ƒ Over-Voltage and Under-Voltage Protections
ƒ Ultra-Low Power Dissipation with No Load
ƒ Universal Input Range: 80~265VRMS
ƒ No Inductor Required
ƒ Low Components and Cost
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, over-
voltage protector, under-voltage protector, and current-
limit circuit onto a monolithic IC.
Applications
ƒ Non-Isolation AC/DC Converter
ƒ Home Appliance
