pkf 4000 i 3?7 w dc/dc power modules 48 v input series the macrodens 3 C7 w pkf 4000 i series true com- ponent level on-board dc/dc power modules are intended as distributed power sources in decentralized C 48 v and C 60 v dc power systems. utilization of thick film technology and a high degree of silicon integration has made it possible to achieve a mtbf of more than 4.9 million hours. the high reliability and the very low height of these dc/dc power modules makes them particularly suited for information technology and telecom (it&t) applications, with board spacing down to 15 mm or 0.6 in. the over-moulded rugged design makes them also suitable for other demanding industrial applications. they are optimized for free convection cooling and have an operational ambient temperature range in compliance with present and future application needs, including non temperature controlled environments. the mechanical design offers the choice of surface mount or through-hole versions, delivered in ready-to-use tubes, trays or tape & reel package and compatibility with semi and fully aqueous cleaning processes. the pkf series is manufactured using highly auto- mated manufacturing lines with a world-class quality commitment and a five-year warranty. ericsson microelectronics ab has been an iso 9001 certified supplier since 1991. for a complete product program please reference the back cover. patents us: d357901 de: m94022763 ? smd and through-hole versions with ultra low component height 8.0 mm (0.315 in) 83% efficiency (typ at 5v) 1,500 v dc isolation voltage mtbf > 4.9 million hours at +50c pin temperature (+40c ambient) low emi in conformance with class a in cispr 22 and fcc part 15j

C72.0v respectively. at input voltages exceeding 72v (abnormal voltage) the power loss will be higher than at normal input voltage and t p must be limited to max +85c. absolute max continuous input voltage is 75 vdc. output characteristics will be marginally affected at input voltages exceeding 72 v. 3) for more information see page 5. 4) the power modules will operate down to v i 36 v, when v i decreases, but will turn on at v i 38 v, when v i increases (see also operating information). 5) the test is applicable for through-hole versions. absolute maximum ratings characteristics min max unit t p pin temperature at full output power 1) ?45 +95 c t s storage temperature ? 55 +125 c v i continuous input voltage 2 ) ? 0.5 + 75 v dc v adj output adjust voltage pin 8, 9 ? 5 + 40 v dc v rc remote control voltage pin 10, 11 ? 5 + 40 v dc w tr transient input energy 3) 0.1 ws 1,500 v dc isolation voltage (input to output test voltage) v iso stress in excess of absolute maximum rat- ings may cause permanent damage. absolute maximum ratings, sometimes referred to as no destruction limits, are normally tested with one parameter at a time exceeding the limits of output data or electrical charac- teristics. if exposed to stress above these limits, function and performance may de- grade in an unspecified manner. environmental characteristics characteristics frequency 10?500 hz amplitude 0.75 mm acceleration 10 g number of cycles 10 in each axis vibration (sinusoidal) jesd 22-b103 (iec 68-2-6 f c ) test procedure & conditions frequency 10?500 hz acceleration density spectrum 0.5 g 2 /hz duration 10 min in 3 directions reproducability medium (iec 62-2-36) mil-std-883 method 2026 (iec 68-2-34 e d ) random vibration peak acceleration 200 g shock duration 3 ms shock (half sinus) jesd 22-b104 (iec 68-2-27 e a ) temperature 85c humidity 85% rh duration 1000 hours temperature ?40c?+125c number of cycles 500 temperature, solder 260c duration 10?13 s temperature change accelerated damp heat solder resistability 5) jesd 22-a104 (iec 68-2-14 n a ) jesd 22-a101 (iec 68-2-3 c a with bias) jesd 22-b106 (iec 68-2-20 t b 1a) duration 96 h temperature 35c concentration 5 % iec 68-2-11 k a aggressive environment input t p < t p max unless otherwise specified characteristics conditions min typ max unit v i input voltage range 2) 4) 38 72 v v i off turn-off input voltage (see typical characteristics) 30 34.5 36 v v ion turn-on input voltage (see typical characteristics) 36.5 38 v c i input capacitance 1.4 f t p = ?30... +85 c, (v i = 53 v) 25 rc connected to pin 17 (v i = 67 v) 30 mw mw input stand-by power p rc p ii input idling power i o =0,t p = ?30...+85c (v i = 53 v) 130 (v i = 67 v) 170
