DC/DC Converter
Description
DC/DC Converter
TSI-20 Series
Features
Step-down Converter with very high Efficiency (> 91%) 3.
3 VDC or 5.
0 VDC Output, up to 6.
0 A Fast Transient Response Remote ON/OFF Overload Protection Low Output Noise Standby Current only 100 µA Small SIL- or DIP-Package 2 Year Product Warranty 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 3.
3 VDC or 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-20 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.
