DESCRIPTION With up to 120 watts of output power, the MOR Series™ 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, –55°C to +125°C, 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 FME28-461 EMI filter to pass MIL-STD-461C, CE03 requirements. The MOR Series converters incorporate a single-ended forward topology which uses a constant frequency Pulse Width Modulator 1.7 µΗ 0.5 µΗ 3:2 (PWM) current mode control design and switches at 550 kHz, nominal. The converters also provide short circuit protection by restricting the current to 125% of the full load output current. All models offer two inhibits, one referenced to input common and one referenced to output common. A remote sense function is available on single output models. 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 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. Vo Trim Up: α = , 1.0 ≤ α ≤ 1.1 ( Steady state voltage range is 16 to 40 VDC. Transient range is 40 to 50 V for a maximum of 120 msec. Low voltage 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. All models include a soft-start function to prevent large current draw and minimize overshoot. CASE AND EXTERNAL INPUT FILTERS Internal 500 V capacitors are connected between the case and input common and between the case and output common. See Figure 1. Interpoint’s FME filters are recommended to meet CE03 requirements for reflected input line current. 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. 1, 2, 3 Positive Input Positive Output 10, 11, 12 28V 4, 5, 6 Input Common 1 Positive Input MOR Single or Dual Output FME28-461 EMI Filter Output Common 7, 8, 9 TRIM UP TRIM DOWN RT Positive Output 7 Output Common 8 Negative Output 9 TRIM UP TRIM DOWN FIGURE 4: TRIM – DUAL ) Example: Vo nominal = 5.0, Vo = 4.5, α = 0.9, RT = 150 kΩ 9 8 Sense Return Output Common 10 Trim MOR Dual Output Vo nominal Vo 2.5 – 1 • 20 – 50 (α -1) Example: Vo nominal = 5.0, Vo = 5.25, α = 1.05, RT = 390 kΩ Vo , 0.6 ≤ α ≤ 1.0 Trim Down: α = Vo nominal RT (kΩ) = RT Trim Positive Output 7 Positive Sense 10 FIGURE 3: TRIM – SINGLE Trim Formulas RT (kΩ) = 50 • α – 30 1–α POSITIVE INPUT AND INPUT COMMON 3 MOR Single Output On dual models the positive output is regulated and the negative output is transformer coupled (cross-regulated) to the positive output.

Do not exceed 110% of Vout and maximum output power. SHARE (PARALLELING) By using the Share pin, up to five single or dual converters may be paralleled for a total output power of over 500 watts (90% Pout / converter, max.). 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. POSITIVE OUTPUT, NEGATIVE OUTPUT AND OUTPUT COMMON Output current is 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.
