In my application, I am generating 7.5V from TPS5430 (Buck) regulator and to generate -5V, I am assigning inductor's one leg to input of 7905 for -5V o/p.
Circuit is shown. U14 is TPS5430 and U15 is 7905.
Is this a correct implementation to get -5V from pulsating DC?
I have seen this arrangement somewhere in design and trying to apply in my circuit.
