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.
