Hello,
I found a component that may be suitable for my application the LTC1624 (please see the DS in this attached). I don't understand very well how it works this electronic assembly :
Is it possible to delete M2/M3 and R3 to have something simpler. I have only +12V (comes from the battery voltage) and I need -5V with 1A to the ouput. Thank you for your helps.
Regards

You can use this schematic and adjust accordingly to satisfy your specification.
After working under LTpowerCAD I lost all the schematics of the simulation. Can I work with LTspice (that I know a little better). ? I think it's the same unless I am mistaken.
Under Mouser I can see 2 models for this component, I think I must take the second model Spice2 Model for 'MBRS340T3' and not PSpice I suppose ?
Do you have links or information to import components under LTspice for simulation ? Thank you for your feedback

Hi,
After drawing the circuit I don't get -5V but -6V.
Something is wrong but I don't know where. But after the DS normally I'll have -5V with a supply +12V
I just removed the following components : M3/M2/R3 and Shutdown. Do you have a idea where is my mistake ? Please see in this attached my simulation.

Thank you Jhun,
But my goal is to find a to find a circuit with a negative voltage at the output (-5V). Do you how I guess I have to calculate the component values to get the -5V. I found this electronic assembly but it is enough that I adapt a little to find the -5V right ?
Thank you for your helps

The referenced ground is the VNEG output.
Sorry but I can't see the VNEG output in your schematic. Where it's (sorry I'm a beginner under LTspice).
Where must I take my probe to see the negative voltage ?
