TPS544E27EVM 4V to 18V, 40A Step-Down Converter
Evaluation Module
Description
The TPS544E27EVM is an evaluation module for the
TPS544E27 DC/DC synchronous buck converter with
a digital PMBus
®
and a series voltage identification
(SVID) interface to accommodate Intel
The evaluation module accepts an 8V to 16V input
and can deliver an output current up to 40A. The
converter uses D-CAP+
™
transient response, using less output capacitance to
save board space.
