Application & Notes
UCC2897RTJR by Texas Instruments is a Flyback, Forward Converter IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to N/A, output adjustable. The 20-WFQFN 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.
