Application & Notes
MAX634ESA by Rochester Electronics, LLC is a Buck-Boost IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 16.5V, output -2.6V. The 8-SOIC (0.154", 3.90mm 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.
