... In view of the high efficiency of the down converter for an input voltage range the iC-WD family is well-suited for industrial applications which require a stabilised 5 V resp. 3.3 V power sup- ply with minimal power dissipation and few compo- nents. Switching transistor, free-wheeling diode and oscil- ...

... In general, fluctuations occur in the clock frequency at the time constants of the charging and discharging phase, which in turn depend on the of supply voltage and the load current. Since no current gap occurs, the cut-off current may be lower than during intermittent flow (at the same load) ...

... The blocking capacitors of supply voltage VB are to be placed as close as possible to pins VB and GND. The capacitors for the outputs VCC and VCCA should be placed directly by the load and not directly by the iC to also block interferences which are coupled via the wiring to the load. A ground plane should be cut out ...
