8.1 Application Information

The TPSM82480 is a switched mode step-down converter module, able to convert a 2.4-V to 5.5-V input voltage into a lower 0.6-V to 5.5-V output voltage, providing up to 6 A continuous output current. It needs a minimum amount of external components. Apart from the output and input capacitors, additional resistors or capacitors are only needed to enable features such as soft-start timing, adjustable and selectable output voltage as well as power good and/or thermal good confirmation. The required power inductors are integrated inside the TPSM82480. The inductors are shielded and have an inductance of 0.47 µH with approximately a +/- 20% tolerance.
