MCH SERIESTM SINGLE & DUAL DC/DC CONVERTERS
With a miniature footprint of just 0.8 square inches, the MCH SeriesTM of DC/DC converters delivers 1.5 watts of output power while saving significant board real estate. The wide input voltage range of 12 to 50 VDC accepts the varying voltages of military, aerospace, or space bus power and tightly regulates output voltages to protect downstream components. Transient protection of 80 volts for up to 120 milliseconds exceeds the requirements of MIL-STD-704A for the 5, 5.2, and 12 volt single models and the 12 volt dual model. The 15 volt single and dual converters will withstand transients of up to 70 volts for up to 120 milliseconds.
INHIBIT FUNCTION
When an open collector TTL logic low is applied to the inhibit terminal, pin 7, the converter shuts down and lowers the output voltage to near zero and input current to as low as 2.3 mA. Leaving the terminal open or applying an open collector TTL logic high will enable the converter.
PROTECTION FEATURES
Undervoltage lockout prevents the MCH Series converters from operating below approximately 8 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. The converters also provide short circuit protection by restricting the current.
CONVERTER DESIGN
MCH Series DC/DC converters incorporate a continuous flyback topology with a constant switching frequency of approximately 370 kHz. Current-mode pulse width modulation (PWM) provides output voltage regulation. Output error voltage is magnetically fed back to the input side of the PWM to regulate output voltage. Regulation is also affected by the load; refer to the Electrical Characteristics tables on the following pages. Dual models regulate the negative output with magnetic coupling to the positive output. Up to 80% of the total load may be on one output providing that the other output carries a minimum of 20% of the total load. The dual models can be used at double the output voltage by connecting the load between positive and negative outputs, leaving the common unconnected. (ex: MCH2805D can be used as a 10 VDC output.)
MIL-STD-461
Use Interpoint's FMSA-461 EMI filter to pass the CE03 requirements of MIL-STD-461C.
CONVENIENT PACKAGING
The MCH Series converters are packaged in hermetically sealed, projection-welded metal cases which provide EMI/RFI shielding.

28 VOLT INPUT - 1.5 WATT
MGH SERIESTM SINGLE & DUAL DC/DC CONVERTERS
The MGH SeriesTM of DC/DC converters delivers 1.5 watts of output power in a labor saving surface mount package. The wide input voltage range of 12 to 50 VDC accepts the varying voltages of military, aerospace, or space applications. Single output converters feature outputs of 5, 12, or 15 volts while dual output models feature outputs of 5, 12, or 15 volts. Transient protection of 80 volts for up to 120 milliseconds exceeds the requirements of MIL-STD-704A for the 5 and 12 volt single and dual models. The 15 volt single and dual converters will withstand transients of up to 70 volts for up to 120 milliseconds.
PROTECTION FEATURES
Undervoltage lockout prevents the MGH Series converters from operating below approximately 8 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. The MGH Series of converters also provide short circuit protection by limiting the current to approximately 125% of full load.
MIL-STD-461
Use Interpoint's FMGA-461 EMI filter to pass the CE03 requirements of MIL-STD-461C.
CONVERTER DESIGN
MGH Series DC/DC converters incorporate a continuous flyback topology with a constant switching frequency of approximately 370 kHz. Output voltage regulation is accomplished on the primary side using current-mode pulse width modulation (PWM). Regulation is affected by the output load; refer to the specifications tables for more information. For dual output models, up to 80% of the total load may be on one output providing the other output carries a minimum of 20% of the total load. The dual models can be used at double the output voltage by connecting the load between positive and negative outputs, leaving the common unconnected. As an example the MGH2805D (5 volt dual output) can be used as a 10 VDC output.
SURFACE MOUNT PACKAGE
MGH DC/DC converters can be surface mounted with pick-andplace equipment or manually. It is recommended that the case be attached with flexible epoxy adhesive or silicone which is thermally conductive (>1 watt /meter/K). Internal components are soldered with SN96 (melting temperature 221C) to prevent damage during reflow. Maximum reflow temperature for surface mounting the MGH converter is 220C for a maximum of 30 seconds. SN60, 62, or 63 are the recommended types of solder. Hand soldering should not exceed 300C for 10 seconds per pin. The hermetically sealed metal cases are available in two different lead configurations. See case B for dimensions and options.
INHIBIT FUNCTION
When an open collector TTL logic low is applied to the inhibit terminal, pin 18, the converter shuts down and lowers the output voltage to near zero and input current to as low 2.3 mA. Leaving the terminal open or applying an open collector TTL logic high will enable the converter.

Notes: 1. Guaranteed by design, not tested. 2. Specified at 50% balanced load. 3. Lin = 2 H. 4. Maximum duration of short circuit: 25C-- 90 seconds, 125C - 30 seconds. 5. Load fault is a short circuit (<50 mohms). Recovery is into resistive full load, with one output shorted at a time.
6. Transition 10 s. Recovery = time to settle to within 1% of Vout final value. 7. Max. spec indicates 80% of the converter's total power, available from either output. 8. Specification applies to both + and - Vout. 9. Although no minimum load is required, at no load the output voltage may increase up to 15%.
