TSI-5.0S2R0FM

DC/DC Converter TSI-10 Series 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 10 Watt 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.
