1.1 Background
This TPS6220XEVM uses a TPS6220X buck converter to step down 2.5-V or
higher input voltages. This EVM operates over an input voltage range of 2.5 V
to 6 V. The goal of the EVM is to demonstrate the small size of the TPS6220X
power supply solution and provide flexibility in interchanging the supporting
passive components.
The TPS62203EVM uses a TPS62203 fixed 3.3-V output buck converter. The
TPS62200EVM uses a TPS62200 adjustable output buck converter and the
appropriate feedback components to provide 1.8-V. Both EVMs include an
enable jumper that allows the user to disable the device.

1.3 Modifications
Because the primary goal of the EVM was to demonstrate the small size of the
TPS6220X power supply solution, capacitors and inductors with small
footprints were chosen. These capacitors and inductors were carefully
selected to maximize efficiency and minimize ripple. Changing components
could improve or degrade EVM performance.
