page 1 of 3 dc/dc converters tsr 0.5sm series, 0.5 a switching regulator features compact smd package very high effciency up to 97% excellent line / load regulation low standby current operating temperature range C40 to 90c over-temperature protection remote on/off input adjustable output voltage short circuit protection moisture sensitivity level 2 as per ipc j -std - 020 d.1 3-year product warranty tsr-0.5sm is a series of step-down nonCisolated switching regulators in compact sip package. these converters are an ideal alternative to lm78 linear regulators when energy effciency is a parameter of the design. the high effciency up to 97 % allows full load operation up to +80c (+90c with 50% load) ambient temperature without the need of forced aircooling. excellent output voltage accuracy and low standby current are other features that - distinguish switching regulators from linear regulators. order code input voltage range 1) output voltage output current effciency typ. nominal trim range 2) max. @ vin min. @ vin 32vdc tsr 0.5-2415sm 4.75 C 32 vdc 1.5 vd c 1.4 C 2.5 vdc 0.5 a 73 % 63 % tsr 0.5-2418sm 1.8 vd c 1.5 C 3.0 vdc 82 % 71 % tsr 0.5-2425sm 2.5 vdc 1.5 C 3.0 vdc 87 % 77 % tsr 0.5-2433sm 3.3 vdc 3.0 C 5.5 vdc 91 % 81 % tsr 0.5-2450sm 6.5 C 32 vdc 5.0 vdc 3.0 C 8.0 vdc 94 % 86 % tsr 0.5-2465sm 8 C 32 vdc 6.5 vdc 3.3 C 11.0 vdc 95 % 88 % tsr 0.5-2490sm 11 C 32 vdc 9.0 v d c 4.5 C 12.6 vdc 96 % 92 % tsr 0.5-24120sm 15 C 32 vdc 12 vd c 4.5 C 13.5 vdc 97 % 94 % tsr 0.5-24150sm 18 C 32 vdc 15 vd c 4.5 C 15.5 vdc 97 % 95 % models 1) for input voltage higher 24 vdc an input capacitor 22 f/ 50 v is required 2) input voltage must be higher than output voltage set:>1.5 v for 3.3C5.0v and >3 v for 6.5C15.0v http://www.tracopower.com
