Application & Notes
RT5701GCP by Richtek USA Inc. 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 0.3V. The 14-TSSOP (0.173", 4.40mm Width) Exposed Pad 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.
