Application & Notes
LM2578AN by Rochester Electronics, LLC is a Boost, Buck IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 40V, output 1V. The 8-DIP (0.300", 7.62mm) 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.
