Application & Notes
BD93291EFJ-E2 by Rohm Semiconductor is a Buck IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 26V, output 0.8V (5V). The 8-SOIC (0.154", 3.90mm 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.
