High Output Voltage Accuracy: 2% .. Output Voltage: 5V .. Low Ground Current: < 2.0mA .. Ultra-Fast Line and Load Transient Response .. Hysteretic Thermal and Current-Limit Protections .. Over-Voltage and Under-Voltage Protections .. Ultra-Low Power Dissipation with No Load .. Universal Input Range: 80~265VRMS .. No Inductor Required .. Low Components and Cost Applications .. Non-Isolation AC/DC Converter .. Home Appliance 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.

Figure 18. Typical Waveforms VDD Pin Over-Voltage Protection After startup, FSAR001 turns on the OVP function. During conduction angle interval, the VDD voltage has two kinds of behavior. One is that if the VDD capacitor recharges to OVP trigger point (8.5V for 5V version), the FSAR001 turns off the power MOSFET to limit the maximum VDD voltage. The other is that if the voltage of...
