TPS2530DBVR
限流配电开关 Current-Limited, Power-Distribution Switches
DESCRIPON
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.
