Introduction
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 can also 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 pro-
vides overcurrent protection. To demonstrate this hot-swap controllability at
high-voltage systems, an evaluation module has been developed, as present-
ed in this user’s guide. The evaluation module (EVM) can help designers eval-
uate the hot-swap controller and simulate hot-insertion and hot-removal ac-
tions under varied conditions.
Users will need a 48-V dc voltage supply to test the operation of the EVM.
