xes the versatile uhe, 12-30w dc/dc converters offer numerous electrical and mechanical options. per the ordering guide on page 2, the trailing dxx or qxx (where xx stands for 12, 24 or 48v in ) in each part number pertains to the base part number. part-number suf? xes are added after this input identi? cation, indicating the selection of standard options. the resulting part number is a "standard product" and is available to any customer desiring that particular combination of options. the on/off control function on pin 4 employs a positive logic (on = open or "high," no suf? x). to request a negative logic on this pin/function, add an "n" suf? x to the part number. standard models have no pins in the pins 5 and 8 positions. for 5-10a models (1.2-5v out ), sense pin/functions can be added to these positions (see pinout p52) by adding an "r" suf? x. an "nr" suf? x can be added for both negative-logic and sense-pin options. see below. suf? x description blank positive logic on/off control function (pin 4), v out trim (pin 9), no sense pins, pin length 0.2 inches (5.08 mm). n add negative logic on the on/off control function, vout trim (pin 9), no sense pins. r positive logic on the on/off control function, v out trim (pin 9), sense pins in the pin 5 and pin 8 positions (available for low v out models only). available under special order. nr negative logic on the on/off control function, v out trim (pin 9), +/C sense pins in the pin 5 and pin 8 positions (available for low v out models only). available under special order. alternate pin lengths are available under special order t alternate trim con?

gurations available on uhe, 12-30w dc/dcs. because designating each of them with a standard part-number suf? x is not always feasible, such are designated by mps in assigning a 5-digit adaptation code after the part-number suf? xes. contact mps directly if you are interested in your own set of options/adaptations. our policy for minimum order quantities may apply. consequently, the following products are offered for sale: uhe-5/6000-d48n-30749 uhe-5/6000-d48n-30749-y (rohs-5) standard product, 48v in , 5v/6a output with negative logic on the on/off control function, modi?

the on/off control is designed to be driven with open-collector (or equivalent) logic or the applica- tion of appropriate voltages (referenced to Cinput (pin 2)). applying a voltage to the on/off control pin when no input voltage is applied to the converter can cause permanent damage. see remote on/off control for more details. ?

the current-limit-inception point is the output current level at which the converter's power-limiting circuitry drops the output voltage 2% from its initial value. see output current limiting and short-circuit protection for more details. ? for start-up-time speci? cations, output settling time is de? ned as the output voltage having reached 1% of its ? nal value at maximum load current. ? mtbfs are calculated using telcordia sr-332 method 1 case, ground ?
