page 1 of 3 dc/dc converters tsr-3 series, 3 a features high performance 3 amp. switching regulator suitable for positive & negative output circuit high effciency up to 95 % adjustable output voltages wide input voltage ranges 2.5C5.5, 4.5C14 and 10C30 vdc over-temperature protection short circuit protection remote on/off input low output ripple & noise 3-year product warranty the tsr 3 models are non isolated step down switching regulators. since production may 2013 they can also be operated with negative output voltage. they come in a very compact open frame package of 15.5 x 9.4 x 6.2mm. the high effciency of up to 95% admits a full load operation up to 50c and up to 85c with 50% current reduction. a low standby current, a very wider input range and no requirement for heatsink give these switching regulators a signifcant advantage over linear regulators. togther with a remote on/off input and protection against short circuit and over temperature the tsr 3 series models are ideal point of load regulators for high reli - able and energy critical applications. order code * input voltage range output voltage adjustable 6) output current max. effciency typ. positive output circuit tsr 3-0533 2.5 C 5,5 vdc 1) 0.6 C 3.3 vdc 95 % at 2.5 vdc tsr 3-1250 4.5 C 14 vdc 2) 0.59 C 6.0 vdc 93 % at 3.3 vdc tsr 3-2450 10 C 30 vdc 3) 3.0 C 6.0 vdc 3 a 91 % at 5.0 vdc tsr 3-24150 10 C 30 vdc 3) 5.0 C 15 vdc 95 % at 12 vdc negative output circuit tsr 3-1250 4.7 C 13 vdc 4) -0.59 C -6.0 vdc 1.5 a at |vout| >3.3 vdc 2.2 a at |vout| <3.3 vdc 90 % at -3.3 vdc tsr 3-2450 10 C 27 vdc 5) -3.0 C -6.0 vdc 2.2 a 90 % at -5.0 vdc tsr 3-24150 10 C 25 vdc 5) -5.0 C -15 vdc 1.2 a 91 % at -12 vdc models * suffx a for models with angular pins (see dimensions), availability on demand, no stocking item. 1) input voltage must be at least 0.5 v higher than output voltage 2) input voltage must be at least 2.0 v higher than output voltage, max. 9 vdc if output is <0.9 vdc 3) input voltage must be at least 3.0 v higher than output voltage 4) max. input voltage = 14-|vout| 5) max. input voltage = 30-|vout| 6) open trim input = min. output voltage http://www.tracopower.com
