High Side Switch Motherboard Evaluation Module
ABSTRACT
The HSS-MOTHERBOARDEVM evaluation module is designed to evaluate the < 50-mΩ Ron devices in TI's
high side switch portfolio. These devices include TPS27SA08, TPS1HA08-Q1, TPS2HB08-Q1, TPS2HB16-Q1,
TPS2HB35-Q1, and TPS2HB50-Q1. This board does not come with the devices populated but allows any of the
devices to be soldered down on the sample daughter card and used in the main motherboard. This user's guide
provides the connectors and test point description, schematic, bill of materials (BOM), and board layout of the
EVM.
Note
This EVM does NOT come with devices populated on the board. The user MUST order samples
separately.
