TPS2530 - Texas Instruments

TPS2530 Power-Distribution Switches

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 currentlimit 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-l.
