dc-dc converters 10.8-15 w high efficiency dc-dc converters 1 2 year warranty sxn15 series single output ? high efficiency topology, 87% typical at 5 v ? wide operating temperature, up to and exceeding 70 ?c (natural convection) ? 90% to 110% output trim ? no minimum load ? overvoltage protection ? remote on/off control ? available rohs compliant the sxn15 is a new high efficiency open frame isolated 15 watt converter series in an industry standard footprint. the first four models in the series feature an input voltage range of 33 vdc to 75 vdc and are available in output voltages of 5 v, 3.3 v, 2.5 v and 1.8 v. the output voltage on each model is adjustable from 90% to 110% of the nominal value. typical efficiencies for the models are 87% for the 5 v, 86% for the 3.3 v, 85% for the 2.5 v and 83% for the 1.8 v version. the sxn15 series also has a remote on/off capability with active high or active low logic. overcurrent and overvoltage protection features are included as standard. with full international safety approval including en60950 and cul1950, the sxn15 reduces compliance costs and time to market. all specifications are typical at nominal input, full load at 25 c unless otherwise stated output specifications voltage adjustability 90% to 110% total error band (see note 11) 3.5% max. line regulation 1.8 v and 2.5 v models 0.5% max. low line to high line 3.3 v and 5 v models 0.1% max. load regulation 1.8 v model 2.0% max. full load to min. load 2.5 v model 1.5% max. 3.3 v and 5 v models 0.5% max. minimum load 0% overshoot 1.8 v and 2.5 v models 3.5% max. at turn-on and turn-off 3.3 v and 5 v models none undershoot none ripple and noise 1.8 v and 2.5 v models 40 mv pk-pk (see note 1) 14 mv rms 5 hz to 20 mhz 3.3 v and 5 v models 70 mv pk-p 20 mv rms transient response 1.8 v and 2.5 v models 150 mv (see note 2) 3.3 v and 5 v models 100 mv typ. deviation 400 s recovery to within total error band input specifications input voltage range 48 vin nominal 33-75 vdc input current no load 35 ma max. remote off 25 ma max. input current (max.)
