Description

1 Description
The TPS546D24SEVM-2PH is a two-phase buck design using two stacked TPS546D24S devices. The
TPS546D24SEVM-2PH is designed for a nominal 12-V bus and to produce a regulated 0.8-V output at up
to 80 A of load current. The TPS546D24SEVM-2PH is designed to demonstrate stacking operation of the
TPS546D24S in a two-phase, low-output voltage application while providing a number of test points to evaluate
the performance of the devices. The TPS546D24SEVM-2PH can be modified to single-phase buck converters
by changing the components assembled. See
configuration.

1.1 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the
TPS546D24SEVM-2PH. Observe all safety precautions.
!
The circuit module has signal traces, components, and component leads on the bottom of the board.
This may result in exposed voltages, hot surfaces, or sharp edges. Do not reach under the board
during operation.
The circuit module may be damaged by over temperature. To avoid damage, monitor the
temperature during evaluation and provide cooling, as needed, for your system environment.
Some power supplies can be damaged by application of external voltages. If using more than
1 power supply, check your equipment requirements and use blocking diodes or other isolation
techniques, as needed, to prevent damage to your equipment.
The communication interface is not isolated on the EVM. Be sure no ground potential exists between
the computer and the EVM. Also be aware that the computer is referenced to the battery- potential of
the EVM.

1.2 Typical Applications

Tip and Barrel Measurement
Warning The TPS546D24SEVM-2PH circuit module may become hot during operation due
to dissipation of heat. Avoid contact with the board. Follow all applicable safety
procedures applicable to your laboratory.
Caution Do not leave the EVM powered when unattended.
