This new generation of step-down converters provides designers with a
cost-effective solution for converting 8 VDC to 27 VDC voltage down to

1.25 VDC to 5 VDC. To achieve highest efficiency, these dc/dc convert­ers are using adwanced circuit techniques , as amorphous ferrite, solid
aluminum capacitors and a synchronous commutation IC.

The TSI-24 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 required.
