Page 10: Background
Background 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. -

Input/Output Connect 2.1 Input/Output Connect Figure 2–1 highlights the key connection points of the TPS6220XEVM. These connection points are described in the following paragraphs. 2.1.1 J1–Vin This is the positive connection to the input power supply. The leads to the input supply should be twisted and kept as short as possible. -
Page 13: Evm Operation
EVM Operation 2.2 EVM Operation As shown in Figure 2–1, an input power supply and a load must be connected to the appropriate EVM connectors in order for the EVM to operate. The absolute maximum input voltage is 7 V. The TPS6220X is designed to operate with a maximum input voltage of 6 V. -

Page 15: Layout
Layout 3.1 Layout Board layout is critical for all switch mode power supplies. Figures 3–1, 3–2, and 3–3 show the board layout for the SLVP211 PWB. The switching nodes with high frequency noise are isolated from the noise sensitive feedback cir- cuitry and careful attention has been given to the routing of high frequency cur- rent loops. -
