9.1 Application Information

The TPS6282x is a switched mode step-down converter, able to convert a 2.4-V to 5.5-V input voltage into a lower 0.6-V to 4-V output voltage, providing up to 3A continuous output current (TPS62823). It needs a very low amount of external components. Apart from the inductor and the output and input capacitors, additional parts are only needed to set the output voltage and to enable the Power Good (PG) feature.
