SLVU047A February 2001 – March 2022 TPS2330 , TPS2331 , TPS5102
The TPS2330/TPS2331 is a Texas Instruments hotswap controller that eliminates high-frequency hot-plug or hot-removal transients, reduces inrush cur- rent, and provides overcurrent protection. The TPS5102 is a dual-channel DC-to-DC controller, designed for notebook PC power but suitable for many other DC/DC applications. The InfiniBand Trade Association (IBTA), led by seven computing-industry leaders and supported by more than 200 computer, network and electronics companies, is developing a new common I/O specification to deliver a channel-based, switched-fabric technology that the entire industry can adopt.
One of the core components of an InfiniBand system is an InfiniBand module or card, and a hot-swappable power-management solution is essential in each InfiniBand module/card. Using the TPS233x hot-swap controller and the TPS5102 DC/DC controller achieves the required power management specified in Infiniband Specification 1.0 released in October 2000.
The evaluation module (EVM) and interface card can help designers evaluate the devices and simulate hot-insertion and hot-removal actions under varied conditions.
Users need a dc voltage supply to test the operation of the EVM.
