Reference Design - TPS2490, 12Vout 60A Hotswap using TI's CSD17570Q5B NexFETs


Design files


This circuit is a hot swap design using the TPS2490 hot swap controller with power limiting and two 30V CSD17570Q5B NexFETs. The system can be used in security servers to give the ability to plug-in line cards when the system is up and running. Constant current start-up using dV/dt control is implemented to keep the inrush current between 1-A and 2-A.

Circuit can sit inside a line card side.

Vin = 12V, ILoad = 60A
