the 1500ur series is a family of miniature 15w dc/dc converters specifically designed for board mount power distribution applications where space is critical, but performance and power cannot be sacrificed. standard features include an ultra-wide 4:1 input voltage range, efficiency as high as 83% and continuous short circuit protection by input current limiting. 14 models operate from (4:1) input voltage ranges of 10 to 40 vdc or 18 to 72 vdc and provide tightly regulated outputs of 3.3, 5, 12, 15, 5, 12 or 15 vdc. all models are packaged in a compact, low profile 2 x 2 x 0.4 metal case. d d e e s s c c r r i i p p t t i i o o n n s s 1500ur series ? ? 6 6 s s i i d d e e d d c c o o n n t t i i n n u u o o u u s s s s h h i i e e l l d d i i n n g g ? ? 4 4 : : 1 1 u u l l t t r r a a - - w w i i d d e e i i n n p p u u t t v v o o l l t t a a g g e e r r a a n n g g e e ? ? o o u u t t p p u u t t v v o o l l t t a a g g e e t t r r i i m m ( ( s s i i n n g g l l e e o o u u t t p p u u t t o o n n l l y y ) ) ? ? - - 2 2 5 5 o o c c t t o o + + 7 7 5 5 o o c c o o p p e e r r a a t t i i n n g g t t e e m m p p e e r r a a t t u u r r e e r r a a n n g g e e ? ? efficiency to 83% ? ? 1 1 4 4 0 0 0 0 v v d d c c i i n n p p u u t t / / o o u u t t p p u u t t i i s s o o l l a a t t i i o o n n ? ? 9 9 . . 4 4 w w / / i i n n 3 3 p p o o w w e e r r d d e e n n s s i i t t y y f f e e a a t t u u r r e e s s i i n n p p u u t t c c h h a a r r a a c c t t e e r r i i s s t t i i c c s s o o u u t t p p u u t t c c h h a a r r a a c c t t e e r r i i s s t t i i c c s s unit/comments input voltage 20 vdc input models vdc 36 vdc input models vdc input fuse requirements 20 vdc input models ma; slow blow type 36 vdc input models ma; slow blow type reverse polarity input amp current input filter lc type single & dual output dc/dc converter min 10 18 typ 20 36 2000 1000 max 40 72 12 g g e e n n e e r r a a l l c c h h a a r r a a c c t t e e r r i i s s t t i i c c s s unit/comments switching frequency khz isolation voltage vdc, 1 minute isolation resistance mohm, 500vdc isolation capacitance pf, 100khz, 1volt mtbf (mil-hbk-217f) thousand hours, +25 o c, ground benign min 130 1400 1000 865 typ 100 max unit/comments mv 1 % 1 %; equal output loads % %; output voltage % 2 % 3 mv; p-p, nom.line fl, 20mhz b.w. using 1 f bypass capacitor %; p-p, nom.line fl, 20mhz b.w. using 1 f bypass capacitor continuous, auto- matic recovery s to within1% error band for 50% step load change % per o c min typ max 100 1.0 2.0 3.0 5.0 1.0 1.0 100 1.25 300 0.02 output voltage accuracy 3.3v outputs all other models voltage balance: dual outputs voltage trim range (single only) 3.3 vout all other models line regulation load regulation ripple/noise 3.3v outputs all other models short circuit protection transient recovery time temperature coefficient 1 = output voltage at nominal line & fl 2 = output voltage measured from minimum input line to maximum 3 = output voltage measured from fl to 10% load >> b-137 www.make-ps.com e-mail:info@make-ps.com
