Application Information

The TPS82084/5 are synchronous step-down converter power modules whose output voltage is adjusted by component selection. The following section discusses the design of the external components to complete the power supply design for several input and output voltage options by using typical applications as a reference.

The required power inductor is integrated inside the TPS82084/5. The inductor is shielded and has an inductance of 0.47 µH with approximately a +/- 20% tolerance. The TPS82084 and TPS82085 are pin-to-pin and BOM-to-BOM compatible, differing only in their rated output current.
