9 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

9.1 Application Information

The TPSM8281x are synchronous step-down converter power modules. The required power inductor is

integrated inside the TPSM8281x. The inductor is shielded and has an inductance of 470 nH with approximately

a ±20% tolerance.

The VCA MagPack package includes a 470nH shielded inductor and shields the entire IC for better EMI

performance. The smaller size and lower height provide higher power density compared to the SIL package.

The 1A, 2A, and 3A VCA versions have the same efficiency and performance, differing only in the output

current rating. The versions are pin-to-pin compatible with higher-current versions: TPSM82814PVCAR (4A) and

TPSM82816PVCAR (6A).

The 3A SIL version has the same efficiency and performance as the 4A SIL version. Both versions differ only in

the output current rating. The versions are pin-to-pin compatible with the higher-current TPSM82816SIER (6A)

version.

9.2.2 Detailed Design Procedure

9.2.2.1 Custom Design With WEBENCH® Tools

Click here to create a custom design using the TPSM8281x device with the WEBENCH® Power Designer.

1. In the part number field start entering the part number if you have a preference and wait until a part list will

appear and populate. If there is no preference leave this field blank.

2. In the next section (auto-filled if you started with a part number) enter the input voltage (VIN), output voltage

(VOUT), and output current (IOUT) requirements.
