The following test equipment is recommended:
• Two-channel storage oscilloscope
• Current probe
• Voltage probe
• An adjustable power supply with a 1.75-V to 6.5-V output and a 10-A output current-limit
• Volt-ohm meter
• A passive or active load capable of handling 3 A.
The user should read the TPS2500/1 data sheet before using the EVM.
Figure 2 shows the EVM test setup for measuring current-limit. Switch S1 enables the power-distribution
switch into a short circuit for this measurement. Figure 3 shows the current waveform for the TPS2500/1
EVM with a shorting jumper populating header J3; Figure 4 shows the current waveform with header J3
unpopulated.
