description
With up to 120 watts of output power, the MOR SeriesTM of DC/ DC converters operates from a standard 28 volt bus and offers a wide input range of 16 to 40 VDC. Full operation over the military temperature range, -55C to +125C, makes the MOR Series an ideal choice for military, aerospace, space, and other high reliability applications. In compliance with MIL-STD-704D, the converters will withstand transients of up to 50 volts for up to 120 milliseconds. Use Interpoint's FMCE-1528 EMI filter to meet the requirements of MIL-STD-461C CE03 and CS01 and/or MIL-STD-461D, E and F CE102 and CS101 levels of conducted emissions. The converters are offered with standard screening, "ES" screening, or fully compliant to "883" MIL-PRF-38534 Class H screening. Standard microcircuit drawings (SMD) are available. The MOR Series converters incorporate a single-ended forward topology which uses a constant frequency Pulse Width Modulator (PWM) current mode control design and switches at 550 kHz, nominal.
Short CirCuit ProteCtion
The converters also provide short circuit protection by restricting the current to 125% of the full load output current, typical.
inhibit FunCtion
All models offer two inhibits, one referenced to input common and one referenced sense return (single output models) or to output common (dual output models). A remote sense function is available on single output models.
trim FunCtion
Using the trim function, the MOR Series can provide any output from 2 to 33 VDC. For example, trimming the two 15 volt outputs of the 15 dual (MOR2815D) to 14 volts, and then stacking the outputs will provide a 28 volt output.
outPut Voltage oPtionS
The MOR Series converters are capable of providing other output voltage options in addition to those characterized on this datasheet. Contact your sales representative to discuss other output voltage options, www.interpoint.com/contacts.
uS PatentS
Interpoint converters may use one or more of the following US patents 5,521,807, 5,694,303, and 5,631,822.

HoW to use tHe Functions inPut Voltage
Steady state voltage range is 16 to 40 VDC. Transient range is 40 to 50 V for a maximum of 120 msec. All models include a soft-start function to prevent large current draw and minimize overshoot.
trim
Both single and dual output models include a trim function. Output voltage can be trimmed from 60% up to 110% of nominal V out . When trimming up, do not exceed the maximum output power. When trimming down, do not exceed the maximum output current. See Figure 2.

emi inPut FilterS
Internal 500 volt capacitors are connected between the case and input common and between the case and output common. Use Interpoint's FMCE-1528 EMI filter to meet the requirements of MIL-STD-461C CE03 and CS01 and/or MIL-STD-461D, E and F CE102 and CS101 levels of conducted emissions. When using an external input filter it is important that the case of the filter and the case of the converter be connected through as low as an impedance as possible. Direct connection of the baseplates to chassis ground is the best connection. If connected by a single trace, the trace should be as wide as it is long. See Figure 1.

inhibit 1 and 2 underVoltage loCkout
Two inhibit terminals disable switching, resulting in no output and very low quiescent input current. The two inhibit pins allow access to an inhibit function on either side of the isolation barrier to help maintain isolation. An open collector is required for interfacing with both of the inhibit pins. Applying an active low to either inhibit pin will inhibit the converter. Leaving the pins open will enable the converter. Inhibit 1 is referenced to Input Common. Inhibit 2 is referenced to Sense Return for single output models and to Output Common for dual output models. The open circuit voltage (unit enabled) for Inhibit 1 is 13 V and for Inhibit 2 it is up to 8 V. Leave the Inhibit pins unconnected if not used. The required active low voltage level is 0.8 V maximum for Inhibit 1 and 0.2 V maximum for Inhibit 2. See Figures 4 and 5.
Undervoltage lockout prevents the units from operating below approximately 15.5 VDC input voltage to keep system current levels smooth, especially during initialization or re-start operations.
SynC in and SynC out
The MOR converters can be synchronized to the system clock by applying an active high sync signal to the Sync In pin. Sync Out can be used to synchronize other components to the MOR converter's switching frequency.

Output current is typically limited to 125% of maximum specified current under short circuit or load fault conditions. Single output models operate from no load to full load. Dual output models with balanced loads operate from no load to full load. For dual models with unbalanced loads, at least 10% of the total output power must be drawn from the positive output at all times, however, the negative output does not require a minimum load. See note 4, cross regulation, under the Electrical Characteristics Tables. Page 3 of 24 MOR Rev K - 20100422

Paralleling (Share Pin) PoSitiVe SenSe, SenSe return
By using the Share pin, up to five single or dual converters may be paralleled for a total output power of up to 540 watts, depending on model. To calculate available power, multiply the number of converters (up to five) by their maximum output power. Multiply the result by 90% for total available power. See Figure 8 for the internal circuit. The converters will share within 10% of each other at 25% to 90% rated power. MOR converters feature true n+1 redundancy for reliability in critical applications. See Figure 9 for the proper connections. All Positive Outputs and Positive Senses should be connected to a common point. All Negative Outputs and Sense Returns should be connected to a common point. The Share pin is referenced to Sense Return. Leave the share pin floating (unconnected) if not used. Also see Figure 9.
A special remote sensing feature maintains the desired output voltage at the load. See Figure 9. When this feature is not used, connect the sense lines to their respective output terminals. See Figure 10. Remote sensing is available on single output models only. Do not exceed 110% of Vout and do not exceed maximum output power.
