1 Setup
This section describes the jumpers and connectors on the EVM as well as how to properly connect, setup,
and use the TPS7A3501EVM-547.
1.1 Input/Output Connectors and Jumper Descriptions
1.1.1 J1 – VIN
Input power supply voltage connector. Twist the positive input lead and ground return lead from the input
power supply and keep them as short as possible to minimize EMI transmission. Add additional bulk
capacitance between J1 and J2 if the supply leads are greater than six inches. For example, an additional
47-µF electrolytic capacitor connected from J1 to ground can improve the transient response of the
TPS7A3501 while eliminating unwanted ringing on the input due to long wire connections.
1.1.2 J2 – GND
Return connector for the input power supply.
