TPS54308: Webench suggesting discontinued inductors from TDK (VLP8040)

Mark Hall

Part Number: TPS54308

Tool/software:

FYI - For Webench design using the TPS54308, the software initially selected the TDK VLP8040 Power Inductor - this should be removed as option as TDK has 'withdrawn' this series completely

It would be great if you could replace it with a footprint compatible part....

I can't find the design parameters that resulted in the VLP8040 being the 'selected' inductor, but did get a design that has the VLP8040 as an alternate;

TPS54308DDCR, vin 8v-28v, output 3.3V at 1a, temp 30degC - select the inductor and the VLP8040 will be the 3rd and 4th option.

See the screen snippet below;
