Application & Notes
MAX1709EUI+ by Analog Devices Inc./Maxim Integrated is a Boost IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 5V, output 2.5V (3.3V, 5V). The 28-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.
