Application & Notes
TL497ACPWR by Texas Instruments is a Buck, Boost IC commonly used in power supply designs, battery-powered devices, and DC-DC conversion modules. Input voltage up to 12V, output ±1.2V. The 14-TSSOP (0.173", 4.40mm 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.
