DC/DC Converter TSI-10N Series 10 Watt Features Step-down Switching Regulator with very high Efficiency Adjustable Output 1.8 – 3.3 VDC or 3.0 – 5.0 VDC Remote ON/OFF Overload Protection Low Output Noise Standby Current only 100 µA Small SIL- or DIL-Package 3 Year Product Warranty This new generation of step-down converters provides designers with a cost-effective solution for converting a 5, 12 or 24 VDC voltage. To achieve highest efficiency, these dc/dc converters are using newest technologies , as amorphous ferrite, solid aluminum capacitors and a synchronous commutation IC. A very high efficiency allows operation without additional heatsink. This product finds many applications in distributed powersystems where a voltage conversion at the point of load is an required.
