DESCRIPTION

The TPS2530 power-distribution switch is intended

for applications such as DisplayPort or USB Port

where heavy capacitive loads and short-circuits are

likely to be encountered. It offers 0.5 A fixed current•

limit thresholds.

The TPS2530 limits the output current to a safe level

by operating in a constant-current mode when the

output load exceeds the current-limit threshold. This

provides a predictable fault current under all

conditions. The fast overload response time eases

the burden on the main supply to provide regulated

power when the output is shorted. The power-switch rise and fall times are controlled to minimize current

surges during turn-on and turn-off.
