EVM User's Guide: TPS513885EVM
TPS513885 Step-Down Converter Evaluation Module
Description
The TPS513885 is a single, D-CAP3
synchronous buck converter requiring a very low
external component count. TPS513885EVM is a
fully assembled and tested circuit for evaluating the
TPS513885 converter. This EVM operates typical
19.5V input, and provides a 5.15V output at 12A.
Integrated low R
power MOSFETs enable high
DS(ON)
efficiency and offer ease of use with a minimal
external component count for space-constrained
power systems.
