General application circuit proposal

C1 and C2 should be placed as close to the device as possible. Low ESR of C2 is

advantageous. Peak currents through C1 and C2 may reach 2 A. Care should be taken that

the resonance of C1, C2 together with supply wire inductances is not the chopping

frequency or a multiple of it.
