Application & Notes
TPS54353PWPR 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 20V, output 1.5V. The 16-PowerTSSOP (0.173", 4.40mm 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.
