| 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 A 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. 15/20 Watt Models Ordercode TSI-3.3S3R0 TSI-3.3S3R0F TSI-5.0S3R0 TSI-5.0S3R0F TSI-3.3S6R0P TSI-3.3S6R0FP TSI-5.0S4R0P TSI-5.0S4R0FP Input voltage range Output voltage Output current max.
