2.2.1 TPS82130

The TPS82130 is a 3-A, step-down converter power module, which integrates the power inductor to achieve a very-small solution size and simple design. The power module accepts up to a 17-V input voltage from its input pin to ground pin. This wide input voltage range is ideally suited for an inverting converter, which, at a minimum, requires a voltage rating of the input voltage plus the output voltage.
