http://www.tracopower.com page 1 of 3 dc/dc converters tsrn-1 series, 1 a switching regulator features sip-package fts existing to-220 footprint suitable for positive & negative output circuit pin compatible with lmxx linear regulators built in flter capacitors operation temp. range C40c to +85c no heat-sink required over-temperature protection short circuit protection wide input range up to 42 vdc excellent line / load regulation low standby current 3-year product warranty the new tsrn-1 series step-down switching regulators are drop-in replacement for ineffcient 78xx linear regulators. a high effciency up to 95 % allows full load operation up to +70c (+85c with derating) ambient temperature without the need of any heat-sink or forced air cooling. the tsrn-1 switching regulators provide other signifcant features over linear regu - lators, i.e. better output accuracy (2 %), lower standby current of ~2 ma and no requirement of external capacitors. they are suitable for positive or negative output circuits. the high effciency and low standby power consumption make these regula - tors an ideal solution for energy sensitive applications. order code 1) input voltage output voltage output current effciency typ. straight pins angular pins range 2) / (nominal) max. @ vin min. @ vin max. positive output circuit tsrn 1-2415 tsrn 1-2415a 4.6 C 42 vdc (12 vdc) 1.5 vd c 77 % 66 % tsrn 1-2418 tsrn 1-2418a 4.6 C 42 vdc (12 vdc) 1.8 vd c 80 % 70 % tsrn 1-2425 tsrn 1-2425a 4.6 C 42 vdc (12 vdc) 2.5 vdc 83 % 75 % tsrn 1-2433 tsrn 1-2433a 4.6 C 42 vdc (12 vdc) 3.3 vdc 87 % 79 % tsrn 1-2450 tsrn 1-2450a 6.5 C 42 vdc (12 vdc) 5.0 vdc 1.0 a 91 % 83 % tsrn 1-2465 tsrn 1-2465a 8.0 C 42 vdc (12 vdc) 6.5 vdc 93 % 86 % tsrn 1-2490 tsrn 1-2490a 10.5 C 42 vdc (12 vdc) 9.0 v d c 94 % 88 % tsrn 1-24120 tsrn 1-24120a 13.5 C 42 vdc (24 vdc) 12 v d c 95 % 91 % tsrn 1-24150 tsrn 1-24150a 16.5 C 42 vdc (24 vdc) 15 vd c 95 % 92 % negative output circuit tsrn 1-2415 tsrn 1-2415a 4.6 C 32 vdc (12 vdc) C1.5 vd c 0.6 a 69 % 64 % tsrn 1-2418 tsrn 1-2418a 4.6 C 32 vdc (12 vdc) C1.8 vd c 0.6 a 72 % 67 % tsrn 1-2425 tsrn 1-2425a 4.6 C 32 vdc (12 vdc) C2.5 vdc 0.6 a 72 % 74 % tsrn 1-2433 tsrn 1-2433a 4.6 C 32 vdc (12 vdc) C3.3 vdc 0.6 a 74 % 77 % tsrn 1-2450 tsrn 1-2450a 6.5 C 31 vdc (12 vdc) C5.0 vdc 0.4 a 79 % 78 % tsrn 1-2465 tsrn 1-2465a 8.0 C 29 vdc (12 vdc) C6.5 vdc 0.3 a 84 % 80 % tsrn 1-2490 tsrn 1-2490a 10.5 C 27 vdc (12 vdc) C 9.0 v d c 0.3 a 85 % 82 % tsrn 1-24120 tsrn 1-24120a 13.5 C 24 vdc (12 vdc) C12 v d c 0.3 a 85 % 85 % tsrn 1-24150 tsrn 1-24150a 16.5 C 21 vdc (12 vdc) C15 vd c 0.2 a 85 % 84 % models 1) same order code for positive and negative output operation, see page 3 for circuits. 2) for input voltage higher 36 vdc an input capacitor 22 f/ 50 v is required
