Part Number: LM5069

Hi Guys

Our customer is using our LM5069 for hot swap. typical 48V. MAX 54V; 50A current load. and they have a 5000uF cap load. So when start up, there will be a inrush current. so need to limit the current. we will set the current limitation and TIMER Cap. here do you have proper mosfet suggestion? how to select this mosfet?

Thanks

Hi Pengfei,

PSMN4R8-100BSE is one of the strong FET to consider for high current applications.

Can you get filled up design calculator and share it with me for review. The design calculator is available at http://www.ti.com/product/LM5069/toolssoftware

The following videos help you on how to use the Design Calculator.
