Application & Notes
2891 by Pololu Corporation is a power conversion IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 5V, output adjustable. The 9-DIP Module 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.
