Introduction
The TPS40322EVM-074 evaluation module (EVM) is a dual-phase single output synchronous buck
converter. The EVM delivers 1.2 V at 30 A from a DC input voltage that ranges from 4.5 V up to 15 V. The
module uses the TPS40322 Dual Output or Two-Phase Synchronous Buck Controller and the
CSD87330Q3D Synchronous Buck NexFET™ Power Block in a 500-kHz application.

Description
TPS40322EVM-074 is designed to convert a regulated 4.5-V
DC
to 15-V
DC
bus into a high-current regulated
1.2-V
DC
output. This output is capable of supplying up to 30 A of load current. The TPS40322EVM-074 is
designed to demonstrate the TPS40322 in a typical regulated bus to dual-phase, single-output, low-
voltage application while providing a number of test points to evaluate the performance of the TPS40322
in a given application.
