The TPSM8286xA is a synchronous step-down converter power module family. The following section discusses the selection of the external components to complete the power supply design. The required power inductor is integrated inside the TPSM8286xA. The integrated shielded inductor has a value of 220 nH with a ±20% tolerance for the RDJ and RDM packages. The RCF MagPack package not only has a 200 nH shielded inductor but also shields the IC for a better EMI performance. The TPSM82864A and TPSM82866A in the RDJ and RDM packages are pin-to-pin and BOM-to-BOM compatible. The TPSM8286xAA0HRDMR devices give a higher efficiency than the TPSM8286xAA0SRDJR devices due to the increased height. For a given package height (RDM or RDJ), the 4A and 6A version give the same efficiency and performance and are different only in the rated output current. The RCF package, using MagPack technology, is less than half the size of the other package versions (RDM and RDJ), thus shrinking the total design size by about 20%, while maintaining the same high efficiency as the other packages.
