(2) noise is measured per calex application notes. (3) turn-on time is defined as the time from the application of power until the output is within 1% of its final value. (4) for long term short circuit protection of the converters, install a slow blow fuse in the input circuit. choose a fuse size that is 125% of your applications actual input current and does not exceed 115% of the full load input current. (5) no minimum load required. (6) short term stability is specified after a 30 minute warm-up at full load, and with constant line, load and ambient conditions. * s r e t e m a r a p t u p n i l e d o m0 0 0 1 . 5 s 2 10 0 5 . 2 1 s 2 10 0 4 . 5 1 s 2 10 0 0 1 . 5 s 4 20 0 5 . 2 1 s 4 20 0 4 . 5 1 s 4 2s t i n u ) 3 1 ( e g n a r e g a t l o v n i m x a m 6 1 . 1 1 0 2 . 3 1 2 3 . 2 2 0 4 . 6 2 c d v w b z h m 0 2 - 0 , ) 2 ( e l p p i r d e t c e l f e r p y t x a m 7 5 1 5 0 1 p - p 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 0 0 7 3 4 0 4 7 3 4 0 2 7 4 5 0 3 3 0 2 0 7 3 3 2 0 6 3 7 2 a m y c n e i c i f f ep y t0 68 69 63 68 69 6% y c n e u q e r f g n i h c t i w sp y t5 5z h k s m 0 0 1 , 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 x a m5 10 3c d v ) 3 ( r o r r e t u p t u o % 1 , e m i t n o - n r u tp y t1 s m e s u f d e d n e m m o c e r ) 4 ( e p y t w o l b w o l s l e d o m0 0 0 1 . 5 s 8 20 0 5 . 2 1 s 8 20 0 4 . 5 1 s 8 20 0 0 1 . 5 s 8 40 0 5 . 2 1 s 8 40 0 4 . 5 1 s 8 4s t i n u e g n a r e g a t l o v n i m x a m 4 0 . 6 2 0 8 . 0 3 4 6 . 4 4 0 8 . 2 5 c d v w b z h m 0 2 - 0 , ) 2 ( e l p p i r d e t c e l f e r p y t x a m 3 0 1 0 1 0 2 p - p 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 8 8 2 9 1 8 1 3 9 1 9 0 3 1 2 0 7 1 6 1 0 9 1 6 1 5 8 1 7 1 a m y c n e i c i f f ep y t2 67 69 60 66 68 6% y c n e u q e r f g n i h c t i w sp y t5 5z h k s m 0 0 1 , 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 x a m5 30 6c d v ) 3 ( r o r r e t u p t u o % 1 , e m i t n o - n r u tp y t1 s m e s u f d e d n e m m o c e r ) 4 ( e p y t w o l b w o l s * s r e t e m a r a p t u p t u o l e d o m 0 0 0 1 . 5 s 4 2 0 0 0 1 . 5 s 2 1 0 0 0 1 . 5 s 8 4 0 0 0 1 . 5 s 8 2 0 0 5 . 2 1 s 4 2 0 0 5 . 2 1 s 2 1 0 0 5 . 2 1 s 8 4 0 0 5 . 2 1 s 8 2 0 0 4 . 5 1 s 4 2 0 0 4 . 5 1 s 2 1 0 0 4 . 5 1 s 8 4 0 0 4 . 5 1 s 8 2 s t i n u e g a t l o v t u p t u o52 15 1c d v ) 5 ( d a o l d e t a r n i m x a m 0 0 0 0 1 0 0 0 5 0 0 0 4 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 5 9 . 4 0 0 . 5 5 0 . 5 0 9 . 1 1 0 0 . 2 1 0 1 . 2 1 0 9 . 4 1 0 0 . 5 1 0 1 . 5 1 c d v 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 2 0 . 0 5 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 2 0 . 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 t0 2 . 0s r h k / % ) 7 ( e s n o p s e r t n e i s n a r tp y t0 2s ) 8 ( e s n o p s e r c i m a n y dp y t0 2 15 50 5k 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 ) 2 ( w b z h m 0 2 - 0 , e s i o n p y t x a m 0 1 0 4 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 0 2 c / m p p ) 0 1 ( p m a l c e g a t l o v r e v op y t8 . 6--c 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 ) 4 ( m u m i x a m e t u n i m 1 , m r e t t r o h s

(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 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. typical performance: (tc = 25 c; full rated load). * 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 e g a k a e l a 0 1 t u p t u o - t u p n i 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 t5 7f 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 8 c ) 1 1 ( e g n a r l a n o i t c n u f e s a c n i m x a m 0 4 - 5 8 c e g n a r e g a r o t s n i m x a m 5 5 - 0 9 c ) 2 1 ( e c n a d e p m i l a m r e h tp y t0 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 m s i s s a h c5 1 s m , 8 s m , 6 s m (12) the case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.
