board mountable dc-dc converters imx 4 series edition 6/4.2000 7/14 output overvoltage protection the outputs of the imx 4 converters are protected against overvoltages by zener diodes. in the event of an overvolt- age on the output, the unit will shut-down and attempt to restart automatically. the main purpose of this feature is to protect against possible overvoltages which could occur due to a failure in the feedback control circuit. the units are not designed to withstand external overvoltages applied to the outputs. connection in series the outputs of single or dual output units can be connected in series without any precautions, taking into consideration that the highest output voltage should remain below 60 v for selv operation. connection in parallel the outputs of several units with equal nominal output volt- age can be connected in parallel. approximate current sharing between 2 or several units is ensured by their load dependent output characteristic. fig. 12 u o versus i o (typ) of single output units (example for 20/40 imx 4-05) fig. 13 u o versus i o (typ) of dual output units ( 15 v), with 30 v load connected to vo+ and vo . 5.25 5.0 4.75 4.5 4.25 4.0 00.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 i o [a] u o [v] 05056 28.5 29 29.5 30 30.5 31 31.5 u o1 + u o2 [v] 20 40 60 80 100 120 140 i o [ma] 0 05057 14 14.5 15 15.5 16 16.5 u o1 [v] 20 40 60 80 100 120 140 i o1 [ma] 0 i o2 = 140 ma i o2 = 14 ma 05058 u o1 , u o2 [v] i o1 i o1 no 05059 12.8 12.4 12 11.6 11.2 030 60 90 120 150 [%] u o2 u o1 thermal considerations if a converter, mounted on a pcb, is located in free, quasi- stationary air (convection cooling) at the indicated maxi- mum ambient temperature t a max (see table: temperature specifications) and is operated at its nominal input voltage and output power, the case temperature t c measured at the: measuring point of case temperature t c (see: me- chanical data ) will approach the indicated value t c max af- ter the warm-up phase. however, the relationship between t a and t c depends heavily on the conditions of operation and integration into a system. the thermal conditions are influenced by input voltage, output current, airflow, tem- perature of surrounding components and surfaces and the properties of the printed circuit board. t a max is therefore only an indicative value and under practical operating con- ditions, the ambient temperature t a may be higher or lower than this value. caution: the case temperature t c measured at the measuring point of case temperature t c (see: mechani- cal data ) may under no circumstances exceed the speci- fied maximum value. the installer must ensure that un- der all operating conditions t c remains within the limits stated in the table: temperature specifications. short circuit behaviour the current limit characteristic shuts down the converter whenever a short circuit is applied to its output. it acts self- protecting and automatically recovers after removal of the overload condition. typical performance curves fig. 14 cross load regulation of dual output units. u o1 versus i o1 (typ) for various i o2 (40 imx 4-1515). fig. 15 flexible load distribution on dual outputs (2 12 v) with load variation from 0...150% of p o1 nom on output 1. output 2 loaded with 25% of p o2 nom .
