The TPS2345 CompactPCIR Hot Swap Power Manager (HSPM) provides highly-integrated supply control of three positive (3.3-V, 5-V, and 12-V) and one negative (12-V) supply rails with a minimum number of external components. A linear current amplifier (LCA) in each of the four device channels provides closed-loop control of load current during insertion and extraction events. This allows the designer to configure the plug-in card's maximum inrush slew rate and magnitude according to the requirements of the CompactPCIR
