FEATURES  
DESCRIPTION  
D
Supports PCI, PCI−X 1.0 and PCI−X 2.0 Slots  
Each TPS2343 contains main supply power  
control, auxiliary supply power control, power  
FETs for 12-V, 12-V and auxiliary 3.3-V supplies,  
VIO control, and digital control for two slots.  
D
Internal Power Switches for −12 V, 12 V, 3.3 V  
Aux  
D
Control for Power FETs for 5 V, 3.3 V, and  
VIO  
The main power control circuits start with all  
supplies off and all outputs are held off until  
PGOOD is asserted, indicating that system  
supplies are valid. Then, when power enable is  
asserted, the control circuit applies constant  
current to the gates of the power FETs, allowing  
each FET to ramp load voltage linearly. Each  
supply can be programmed for a desired ramp  
rate by selecting the appropriate gate capacitor.  
The TPS2343 monitors load current and regulates  
peak current to prevent disturbances to the  
system power rails. If load current remains  
regulated for longer than 5 ms, that slot is latched  
off.
