Application hints
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.
