Application & Notes
TOP258PN 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 8-DIP (0.300", 7.62mm), 7 Leads 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.
