Application & Notes
TPS5401DGQ by Texas Instruments is a Buck IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 42V, output 0.8V. The 10-PowerTFSOP, 10-MSOP (0.118", 3.00mm 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.
