DC/DC Converter TSI-10 Series 10 Watt Features Step-down Switching Regulator with very high Efficiency (> 92%) 1.8 – 3.3 VDC or 5.0 VDC Output, up to 2.0 A Remote ON/OFF Overload Protection Low Output Noise Standby Current only 100 µA Small SIL-, DIP- or SMD-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 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. Models Ordercode Input voltage range Output voltage Output current max.
