page 1 of 3 dc/dc converters tsn-1 series, -1 a switching regulator features non-isolated converter for negative output small size and low profle pin compatible with lm79xx linear regulators no heatsink required high effciency up to 96% operation temp. range C40c to +85c protection against overload, short circuit and over-temperature fixed switching frequency wide input range up to -32 vdc excellent line / load regulation low standby current 3-year product warranty the new tsn-1 series step-down switching regulators are drop-in replacement for ineffcient 79xx linear regulators. a high effciency up to 96 % allows full load op - eration up to +70c (+85c with derating) ambient temperature without the need of any heat-sink or forced air cooling. the tsn-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 negative output circuits. the high effciency and low standby power consumption make these regulators an ideal solution for energy sensitive applications. order code input voltage output voltage output current effciency typ. straight pins angular pins range / (nominal) max. @ vin min. @ vin max. tsn 1-2450 tsn 1-2450a -7.0 C -32 vdc (12 vdc) -5.0 vdc 91.5 % 84.5 % tsn 1-2452 tsn 1-2452a -7.0 C -32 vdc (12 vdc) -5.2 vdc 92.0 % 85.0 % tsn 1-2460 tsn 1-2460a -8.0 C -32 vdc (12 vdc) -6.0 vdc 92.5 % 86.5 % tsn 1-2480 tsn 1-2480a -10.5 C -32 vdc (12 vdc) -8.0 vdc -1.0 a 94.0 % 89.0 % tsn 1-2490 tsn 1-2490a -11.5 C -32 vdc (24 vdc) -9.0 v d c 94.5 % 90.5 % tsn 1-24120 tsn 1-24120a -15 C -32 vdc (24 vdc) -12.0 vd c 96.0 % 92.0 % tsn 1-24150 tsn 1-24150a -18 C -32 vdc (24 vdc) -15.0 vd c 96.0 % 93.5 % models http://www.tracopower.com
