This new generation of step-down converters provides designers with a
cost-effective solution for converting a 5 VDC resp. 12 VDC voltage down
to 1.8 – 3.3 VDC or to 5 VDC. To achieve highest efficiency, these dc/dc
converters are using newest technologies , as amorphous ferrite, solid
aluminum capacitors and a synchronous commutation IC.

The TSI-10 series needs no further external components to operate
within its specifications. A very high efficiency allows operation without
additional heatsink. This product finds many applications in distributed
powersystems where voltage conversion at the point of load is an
advantage.
