Application & Notes
FT440AA by Fremont Micro Devices Ltd is a Buck IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 5.5V, output 0.6V. The SC-74A, SOT-753 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.
