TPS61046EVM-682 Evaluation Module
This user's guide describes the schematic, layout, and operation of the TPS61046EVM-682 evaluation
module.
There are two TPS61046 power circuits in the EVM. U1 is for the adjustable output voltage version, where
the FB pin is connected to the feedback network, so the VOUT can be set from 5 V to 28 V; U2 is for the
fixed 12-V VOUT version as the FB pin is connected to the VIN pin directly. A 1.6 mm × 0.8 mm inductor
is used in this circuit, limiting the input current no higher than 100 mA.
