Fast development of telecommunications and networks has accelerated growth of products with hot-plug capability to ensure that systems are always on. Many hot-swap or hot-plug devices are already available in the worldwide market. However, most such devices are for low-voltage applications, whereas 48-V is a standard voltage in most communication systems. The TPS23xx series of hot-swap controllers are principally designed for low voltage applications, but also can be used in very high voltage systems if appropriately designed.
The TPS2330 is a Texas Instruments hot-swap controller that eliminates high-frequency hot-plug or hot-removal transients, reduces inrush current, and provides overcurrent protection. To demonstrate this hot-swap controllability in high-voltage systems, the TPS2330EVM-184 evaluation module has been developed. The EVM can help designers evaluate the hot-swap controller and simulate hot-insertion and hot-removal actions under varied conditions.
**Additional Equipment Needed:** Users will need a 48-V dc voltage supply to test the operation of the EVM
