features ! low input/output noise operation ! low profile case (0.38") ! isolation capacitance of 50 pf ! extended operating temperature range of -40c to +100c. ! fixed frequency operation ! 5 year warranty description the versatile 5 watt dual output converter is particularly suitable for use in microprocessor systems where 5 volts is the primary power source, and where a low noise plus and minus output voltage is required. the shielded transformer provides low i/o capacitance and high common mode input to output isolation. the low guaranteed output noise of 20mv p-p maximum is achieved by a built-in linear post regulator. available in standard 6 sided shielding, or the -5 model which has 5 sided shielding and is water washable. each converter is completely specified, fully ate tested, contains overload protection, and is covered under calex?s 5 year warranty. 5 watt dual series block diagram t r a h c n o i t c e l e s l e d o m e g n a r t u p n i c d v s t u p t u o c d v s t u p t u o a m n i mx a m b 5 8 1 . 2 1 d 55 7 . 45 2 . 52 1 5 8 1 5 - b 5 8 1 . 2 1 d 55 7 . 45 2 . 52 1 5 8 1 b 0 5 1 . 5 1 d 55 7 . 45 2 . 55 1 0 5 1 5 - b 0 5 1 . 5 1 d 55 7 . 45 2 . 55 1 0 5 1 b 7 6 1 . 5 1 d 55 7 . 45 2 . 55 1 7 6 1 5 - b 7 6 1 . 5 1 d 55 7 . 45 2 . 55 1 7 6 1

(1) to determine the correct fuse size, see calex application notes. (2) no minimum load current is required. (3) short term stability is specified after a 30 minute warm-up at full load, and with constant line, load and ambient conditions. (4) the transient response is specified as the time required to settle from 100% step load change (rise time of step = 2sec.) to a 1% error band. (5) dynamic response is the peak overshoot voltage during the transient response time defined in note 4 above. (6) limited to 10 seconds maximum when both outputs are shorted to common at the same time. (7) the functional temperature range is intended to give an additional data point for use in evaluating this power supply. at the low functional temperature the power supply will function with no side effects, however sustained operation at the high functional temperature may reduce expected operational life. all data sheet specifications are not guaranteed over the functional temperature range. (8) the case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated. * s r e t e m a r a p t u p t u o l e d o m b 5 8 1 . 2 1 d 5 5 - b 5 8 1 . 2 1 d 5 b 0 5 1 . 5 1 d 5 5 - b 0 5 1 . 5 1 d 5 b 7 6 1 . 5 1 d 5 5 - b 7 6 1 . 5 1 d 5 s t i n u e g a t l o v t u p t u o2 1 5 1 5 1 c d v ) 2 ( t n e r r u c d e t a r n i m x a m 0 5 8 1 0 0 5 1 0 7 6 1 a m e g n a r e g a t l o v n i m p y t x a m 0 4 9 . 1 1 0 0 0 . 2 1 0 6 0 . 2 1 5 2 9 . 4 1 0 0 0 . 5 1 5 7 0 . 5 1 5 2 9 . 4 1 0 0 0 . 5 1 5 7 0 . 5 1 c d v e c n a l a b t u p t u o p y t x a m 5 . 0 0 . 1 % d a o l % 0 0 1 - 0 n o i t a l u g e r d a o l p y t x a m 1 0 . 0 7 0 . 0 % n o i t a l u g e r e n i l c d v x a m - n i m = n i v p y t x a m 1 0 . 0 7 0 . 0 % ) 3 ( y t i l i b a t s m r e t t r o h sp y t1 . 0 <% y t i l i b a t s m r e t g n o lp y t2 . 0 a 5 watt dual series dc/dc converters stco #961113, 980129-1 manufacturing company, inc. concord, california 94520 ph: 925/687-4411 or 800/542-3355 fax: 925/687-3333 www.calex.com email: sales@ca lex.com 3 2/2/98 -40 -20 0 20 40 60 80 100 ambient temperature (deg c) 0.0 1.0 2.0 3.0 4.0 5.0 output power (watts) 4.5 watt dual series power derating infinite heat sink still air safe operating area -5 std 0 20406080100 load (%) 40 50 60 70 efficiency (%) 4.5 watt dual efficiency vs load a = 4.75vdc b = 5.0vdc c = 5.25vdc a b c 4.75 4.88 5.00 5.13 5.25 line input (volts) 55 60 65 70 efficiency (%) 4.5 watt dual efficiency vs line input 50% full load 100% full load bottom view side view mechanical tolerances unless otherwise noted: x.xx dimensions: 0.020 inches x.xxx dimensions: 0.005 inches case the 5d12.185b, 5d15.150b and 5d15.167b use a six sided shielded copper case system. it is filled with a silicon rubber compound and the outside is painted black. the seal around the terminals is not hermetic and the unit should not be immersed in any liquid. the 5d12.185b-5, 5d15.150b-5 and 5d15.167b-5 use a 5 sided shielded steel case system. the case is specially tin plated to deter rusting. the assembly is filled with a compound which seals it and will withstand water washing in the typical manufacturing cleaning process. typical performance (tc=25 c; full rated load). n i pn o i t c n u f 1t u p n i + 2t u p n i - 3t u p t u o + 4n m c 5t u p t u o - 5 watt dual efficiency vs line input 5 watt dual efficiency vs load 5 watt dual series power derating * s n o i t a c i f i c e p s l a r e n e g s l e d o m l l as t i n u n o i t a l o s i e g a t l o v n o i t a l o s i t u p t u o o t t u p n i e g a k a e l a 0 1 n i m0 0 7c d v t u p t u o o t t u p n i e c n a t i c a p a c p y t0 5f p l a t n e m n o r i v n e e g n a r g n i t a r e p o e s a c g n i t a r e d o n n i m x a m 5 2 - 0 9 c ) 7 ( e g n a r l a n o i t c n u f e s a cn i m x a m 0 4 - 0 0 1 c e g n a r e g a r o t sn i m x a m 5 5 - 5 0 1 c ) 8 ( e c n a d e p m i l a m r e h t s l e d o m d r a d n a t sp y t0 1t t a w / c s l e d o m 5 -p y t1 1t t a w / c l a r e n e g t h g i e w t i n up y t7 . 1z o s t i k g n i t n u o m5 1 s m & 6 s m
