Application & Notes
L4963D013TR by STMicroelectronics is a Buck IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 46V, output 5.1V. The 20-SOIC (0.295", 7.50mm Width) 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.
