10 watt tc single series block diagram features ! extra wide 3:1 input voltage range, 20-60 vdc ! low noise, highly regulated single outputs ! efficiency 75% for all line conditions ! no derating to 80c case temperature ! six-sided shielded low thermal gradient copper case ! 500 vdc minimum input to output isolation ! overvoltage protected input and outputs ! pulse by pulse digital current limiting ! overtemperature protection circuit ! 5 year warranty description these single output converters are designed for wide input range, low noise, telecommunications, industrial control, medical and instrument applications. the extra wide input range (3:1) is ideal for battery or unregulated input applications. these converters are state-of-the-art 120khz mosfet based designs that provide outstanding line and load regulation. the single outputs are regulated with a high loop gain current mode control method that provides linear regulator type performance. also included is an open collector ttl/cmos compatible logic shutdown pin to control converter operation. the tc single series is protected from output shorts to common by a high speed, pulse by pulse digital, current limit circuit and a thermal overload sensing circuit. 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 c t 0 0 0 2 . 5 s 8 40 . 0 20 . 0 65 0 0 0 2 c t 0 5 8 . 2 1 s 8 40 . 0 20 . 0 62 10 5 8 c t 0 0 7 . 5 1 s 8 40 . 0 20 . 0 65 10 0 7 t u p t u ocd 5f 6 3 1v 8 . 6 2 1f 0 2v 5 1 5 1f 0 2v 8 1

(7) the transient response is specified as the time required to settle from 50 to 75% step load change (rise time of step = 2 sec.) to a 50 mv error band. (8) dynamic response is the peak overshoot voltage during the transient response time defined in note 7 above. (9) the input ripple rejection is specified for dc to 120hz ripple with a modulation amplitude of 1% vin. (10) for module protection only, see also note 4. (11) the logic shutdown pin is open collector ttl, cmos, and relay compatible. the input to this pin is referenced to pin 2, -input and is protected to +100 vdc. (12) case is tied to pin 3, +input. (13) 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 will reduce expected operational life. the data sheet specifications are not guaranteed over the functional temperature range. (14) the case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated. notes * all parameters measured at tc = 25 c, nominal input voltage and full rated load unless otherwise noted. refer to the calex application notes for the definition of terms, measurement circuits and other information. (2) noise is measured per calex application notes. (3) an external capacitor capable of withstanding at least 700 ma rms of 120 khz ripple current must be connected directly across the + and - inputs. suggested capacitors are: sprague electric: 672d686h100dm3c, 68f, 100v 672d127h100et3c, 120f, 100v panasonic: ecea2afe101, 100f, 100v ecea2afe121, 120f, 100v united chemi-con: sxe100vb120m12.5x25ll, 120f, 100v sxe100vb180m12.5x30ll, 180f, 100v sxe100vb220m12.5x35ll, 220f, 100v note:all of the above capacitors are 105 c rated. multiple smaller sized capacitors may be used in parallel as long as their total ripple capability is above 700 ma rms (see irr curve). (4) determine the correct fuse size by calculating the maximum dc current drain at low line input, maximum load and then adding 20 to 25%. a slow blow type fuse is recommended. (5) no minimum load required. * s r e t e m a r a p t u p n i l e d o mc t 0 0 0 2 . 5 s 8 4c t 0 5 8 . 2 1 s 8 4c t 0 0 7 . 5 1 s 8 4s t i n u e g n a r e g a t l o v n i m p y t x a m 0 . 0 2 0 . 8 4 0 . 0 6 c d v w b z h m 0 2 - 0 , ) 3 ( ) 2 ( e l p p i r d e t c e l f e rp y t0 0 7s m r a m d a o l l l u f t n e r r u c t u p n i d a o l o n p y t p y t 5 6 2 0 1 5 6 2 0 1 3 7 2 0 1 a m y c n e i c i f f ep y t8 70 80 8% y c n e u q e r f g n i h c t i w sp y t0 2 1z h k , e g a t l o v r e v o t u p n i m u m i x a m e g a m a d o n s m 0 0 1 x a m5 7c d v e m i t n o - n r u tp y t0 1s m e s u f d e d n e m m o c e r ) 4 ( * s r e t e m a r a p t u p t u o l e d o mc t 0 0 0 2 . 5 s 8 4c t 0 5 8 . 2 1 s 8 4c t 0 0 7 . 5 1 s 8 4s t i n u e g a t l o v t u p t u o52 15 1c d v ) 5 ( t n e r r u c d e t a r n i m x a m 0 0 0 0 2 0 0 5 8 0 0 0 7 a m e g n a r e g a t l o v d a o l % 0 0 1 n i m p y t x a m 0 5 9 . 4 0 0 0 . 5 0 5 0 . 5 0 0 9 . 1 1 0 0 0 . 2 1 0 0 1 . 2 1 0 0 9 . 4 1 0 0 0 . 5 1 0 0 1 . 5 1 c d v n o i t a l u g e r d a o l d a o l l l u f % 0 0 1 - 0 p y t x a m 1 . 0 3 . 0 5 0 . 0 1 . 0 4 0 . 0 1 . 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 5 1 . 0 1 0 . 0 1 . 0 1 0 . 0 1 . 0 % ) 6 ( y t i l i b a t s m r e t t r o h sp y t2 0 . 0% y t i l i b a t s m r e t g n o lp y t2 . 0s r h k / % ) 7 ( e s n o p s e r t n e i s n a r tp y t0 50 0 10 5 1s ) 8 ( e s n o p s e r c i m a n y dp y t5 50 0 10 1 1k a e p v m ) 9 ( n o i t c e j e r e l p p i r t u p n ip y t0 6b d w b z h m 0 2 - 0 , e s i o n p y t x a m 5 3 5 7 0 2 0 5 0 2 0 5 p - p v m t n e i c i f f e o c e r u t a r e p m e t p y t x a m 0 5 0 5 1 c / m p p ) 0 1 ( p m a l c e g a t l o v r e v op y t8 . 65 18 1c d v o t n o i t c e t o r p t i u c r i c t r o h s s t u p t u o l l a r o f n o m m o c d a o l r e v o l a m r e h t d n a t i m i l t n e r r u c m u m i n i m s r u o h 8 , s u o u n i t n o c f o s e d i v o r p
