1 Introduction
The TPS2595EVM eFuse Evaluation Board allows reference circuit evaluation of TI's TPS259520,
TPS259533, TPS259541, and TPS259573 devices.
NOTE: To evaluate other variants from the TPS2595xx family, please order the samples from
www.ti.com separately, and replace existing devices on the EVM as per Table 1 .
1.1 EVM Features
General TPS2595EVM eFuse evaluation board features include:
• 2.7-V to 18-V (TYP) operation
• 0.5-A to 4-A programmable load current limit
• Programmable V
OUT
slew rate control
• Onboard TVS for input transient protection
• Common diode at output prevents negative spike when load is removed
• Overvoltage clamp and cutoff
1.2 EVM Applications
This EVM can be used on the following applications:
• Hot-swap, hot-plug
• SSDs and HDDs
• Industrial systems
• White goods
• Set-top box
• Digital TV
2 Description
The TPS2595EVM eFuse evaluation board enables evaluation of four variant devices (through four
channels) from the TPS2595xx family. The input power port is common for all the four channels and is
applied at T1 and the corresponding outputs are labeled as VOUT1, VOUT2, VOUT3, and VOUT4 at T2
which provides the output connection to the load, Refer to the schematic in
Figure 1 , and the EVM test
setup in Figure 2 . D2, C1 at T1 provides input protection for all four channels.
