Application & Notes
TDL 3-1212 by WEC is a power conversion IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 18V, output adjustable. The 7-DIP Module, 4 Leads 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.
