Application & Notes
MAX1556ETB+T by Analog Devices Inc./Maxim Integrated 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 0.75V (1.8V, 2.5V, 3.3V). The 10-WFDFN 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.
