TPS2596EVM: Evaluation Module for TPS2596xx
1
Introduction
The TPS2596EVM allows reference circuit evaluation of TI's TPS2596xx devices. The TPS2596xx devices
are available with both latching and auto-retry operation. For the TPS25962x variants, in case of an input
overvoltage condition, internal clamping circuits limit the output to a safe fixed maximum voltage which is
pin selectable. The TPS25963x variants provide an option to set a user-defined overvoltage cutoff
threshold.

•
Push button RESET signal
•
Onboard 15-V TVS for input transient protection. The TVS needs to be removed if TPS2596EVM is
intended to operate at input voltages greater than 15 V.
•
Schottky diode at output prevents a negative spike when the load is removed
