Application & Notes
LNK6663K by Power Integrations is a Flyback IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to N/A, output adjustable. The 12-BESOP (0.350", 8.89mm Width), 11 Leads, Exposed Pad package with surface mount mounting is standard for compact designs. Pay attention to input/output capacitor selection and PCB layout — switching regulators are sensitive to trace inductance.
