The units are capable of withstanding short term transients up to 50 volts. 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. Converter Design The MHF+ converters are switching regulators that use a quasi-square wave, single-ended forward converter design with a constant switching frequency of 550 kHz typical. Isolation between input and output circuits is provided with a transformer in the forward path and a temperature compensated optical link in the feedback control loop. See Figure 1. For the MHF+ dual output models, good cross regulation is maintained by tightly coupled output magnetics. Up to 90% of the total output power (80% on 2805D) is available from either output, providing the opposite output is simultaneously carrying 10% of the total output power (20% on 2805D models). Predictable current limit is accomplished by directly monitoring the output load current and providing a constant current output above the overload point. Inhibit Function MHF+ converters provide an inhibit terminal that can be used to disable internal switching, resulting in no output current and very low quiescent input current. The converter is inhibited when an active low of ≤0.8 V is applied to the inhibit pin. The unit is Crane Aerospace & Electronics Electronics Group (Interpoint Brand) PO Box 97005 • Redmond WA 98073-9705 425.882.3100 • [email protected] www.interpoint.com enabled when the pin, which is internally connected to a pull-up resistor, is left unconnected or is connected to an open-collector gate. The open circuit output voltage associated with the inhibit pin is 8.5 to 12 V. In the inhibit mode, a maximum of 4 mA must be sunk from the inhibit pin. See Figure 3. Synchronization An external synchronization feature is included that allows the user to adjust the nominally 550 kHz operating frequency to any frequency within the range of 500 kHz to 600 kHz. This is initiated by applying a signal input of the desired frequency to pin 5. The capacitively coupled sync input will synchronize on a differential signal of as low as 4 volts to as high as 5 V. For single and dual output models, if the sync function is not used, connect the terminal to input common. Short Circuit Protection MHF+ Series single and dual output converters provide short circuit protection by restricting the output current to approximately 115% of the full load output current. The output current is sensed in the secondary stage to provide highly predictable and accurate current limiting, and to eliminate foldback characteristics. Undervoltage Lockout Undervoltage lockout prevents the single and dual output converters from operating below approximately 14 VDC input voltage to keep system current levels smooth, especially during initialization or re-start operations. Page 1 of 23 MHF+ Rev L - 20091113 Crane Aerospace & Electronics Power Solutions MHF+ Single, Dual and Triple DC/DC Converters 28 Volt input – 15 Watt MHF+ Series™ Triple DC/DC converters MHF+ Series™ Triple DC/DC converters provide a wide input voltage range of 16 to 48 VDC delivering 15 watts of total output power with output voltages of +5 and ±12 or +5 and ±15 VDC. The main output, +5 VDC, will supply up to 7.5 watts and the auxiliaries will supply up to 7.5 watts of combined power. Full power operation at -55° C to +125° C plus the ability to withstand transients of up to 80 V for up to 120 milliseconds make these converters an ideal choice for your high reliability systems. Soft Start Feature The soft-start feature provides a controlled 25 milliseconds maximum turn-on to minimize inrush current and reduce overshoot at initial start-up or when inhibit is released. Synchronization MHF+ Triple Series of DC/DC converters incorporate dual-phase, phase-shifted technology with a continuous flyback topology. This design eliminates a minimum load requirement on the main output and eliminates cross regulation effects between the main output voltage and auxiliary output voltages. See Figure 2. The phase-shifted design offers reduced input and output ripple. To meet MIL-STD-461 requirements use an EMI filter, see Figure 5. FMH-461 is the recommended filter. To synchronize the converter’s switching frequency to a system clock apply the clock signal to the sync terminal (pin 7). When multiple converters are powered from a single power source, asynchronous (free run) operation will result in lower peak noise for common spectral peaks, but synchronous operation will eliminate any possibility of interference frequencies in the low audio band. Source impedance of the signal should be less than 100 ohms and the transition time should be less than 100 nanoseconds. The capacitively coupled sync input will synchronize on a differential signal of as low as 4 volts to as high as 5 V. For triple output models, if the sync function is not used, the terminal should be left open. See Figure 4. Inhibit Function Short Circuit Protection Converter Design An open collector inhibit terminal (pin 1) provides shut-down and start-up control. Applying an active low of <0.8 V, referenced to input common, will disable the output of the converter. When inhibited, input current is reduced to 5 mA or less and there is no generation of switching noise. The inhibit terminal typically sinks 3 mA when the converter is inhibited. Leaving the terminal open or pulling it high will enable the converter. Use an open collector interface for active high voltages of up to 11 volts. (Refer to Figure 2 for a connection diagram.) An open collector interface is not required if the active high is in excess of the open circuit voltage of the inhibit terminal (11 volts) but less than 40 volts. See Figure 2. MHF+ Series™ all Models Packaging MHF+ Series of converters are packaged in hermetically sealed metal cases and can be purchased in a flanged or non-flanged case. The flanged option provides increased heat dissipation and also provides greater stability when mechanically secured. On the triple output models, internal current limiting circuitry protects on all three outputs against short circuits. When output power exceeds approximately 130% of maximum output power, the output currents are limited. In addition, separate current limiting circuitry protects each output individually resulting in normal operation of either the main or the auxiliaries, whichever is not in a shorted condition. Undervoltage Lockout Undervoltage lockout prevents the triple output models units from operating below approximately 8.5 VDC input voltage to keep system current levels smooth, especially during initialization or re-start operations.

Notes for Dual Output Models 1. Guaranteed by design, not tested. 2. Up to 13.5 watts, 90% (9.6 watts, 80% for 2805D) of the total output power is available from either output provided that the opposite output is simultaneously carrying 10% (20% for 2805D) of the total output power. One of the outputs must always provide a minimum of 10% (20% for 2805D) of the total output power used to meet cross regulation. Negative Vout cross regulation is referenced to 50%/50% balanced loads (at 100% of total rated output power - full load). 3. The “Total” specification is the maximum combined current/power of both outputs. 4.Effect on –VOUT for the following conditions, A and B: Condition A: +Po = 50% to 10% and –Po = 50% +Po = 50% and –Po = 50% to 10% Condition B, outputs are switched simultaneously between the “From” and “To” conditions: From +Po = 70%, –Po = 30% To +Po = 30%, –Po = 70% Both conditions are referenced to the balanced loads condition: 50%/50% www.interpoint.com 5.Indefinite short circuit protection not guaranteed above 125°C (case) 6.Recovery time is measured from application of the transient to point at which VOUT is within regulation. 7.Response of either output with the opposite output held at half of the total output power. 8. Step transition time >10 µs.
