Application & Notes
UCC28C40QDRQ1 by Texas Instruments is a Buck, Flyback IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to N/A, output adjustable. 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.
