Part Number: LM5066I
I would like for a TI apps engineer do a brief review of my schematic. Is this possible? Thanks Don
Hey Don, long time.
Go to www.ti.com/hotswap and download the Design Calculator tool, it will help you a lot. You need to know the entire system capacitance, even way down stream in DC_DC front ends. Given current level, should not be much Cap. Enter all of the customer specific items. A couple of things right off, the CM chokes have significant DM inductance so you want a unidirectional TVS right at R44 "+" side to clamp Vin during a fault (assuming you need to survive a fault undamaged). Also a Schottky on the output. Both need to handle full short circuit current (which is higher than the SS trip due to a delay that filters nusiance trips). You also need a 1000pF cap at the Diode pin on the LM5066.
