DesCrIPtION

The Interpoint ™ MCH Series™ and MGH Series ™ of dc-dc converters delive r 1.5 watts of output power while saving significant board real estate. The wide input voltage range of to VDC accepts the varying voltages of military, aerospace, or space bus power and tightly regulates output voltages to protect downstream components. Transient protection of volts for up to 120 milliseconds exceeds the requirements of MIL-STD-704A for the and volt single models and the volt dual model. The volt single and dual converters will withstand transients of up to volts for up to 120 millis econds. The converters are offered with standard screening, “ES” screening, or fully compliant to “883” MIL-PRF-38534 Class H screening. See “Table 11: Element Evaluation” on page and “Table 12: Environmental Screening” on page 13. Standard microcircuit drawings (SMD) are available. See “Table MCH SMD Numbers” on page and “Table MGH SMD Numbers” on page Converter Design MCH Series and MGH Series of 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 Table on page and Table on page 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 VDC output.) inhibit FunCtion MCH and MGH converters provide an inhibit terminal that can be used to disable internal switching, resulting in no output voltage and an input current as low as 2.3 mA. The converter is inhibited when the inhibit pin is pulled below 0.8 V and enabled when its inhibit pin is left floating. An external inhibit interface should be capable of pulling the converter’s inhibit pin below 0.8 V while sinking the maximum inhibit current and also allowing the inhibit pin to float high to enable the converter. A voltage should not be applied to the inhibit pin. The open circuit voltage present on the inhibit pin is to ProteCtion Features Undervoltage lockout prevents the converters from operating below approxima tely 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.

+Vin +Vout Case Ground Figure 1: MCh/Mgh bLoCk DiagraM PaCkaging MCH - Down-leaded package The MCH Series converters are packaged in hermetically sealed, projection-welded metal cases which provide EMI/RFI shielding. See “Figure 21: MCH Case Dimensions” on page 10. MGH - Surface mount package The surface mount MGH dc-dc converters can be mounted with pick-and-place 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 compon ents are soldere d with SN96 (melting temperature 221°C) to prevent damage during reflow. Maximum reflow temperature for surface mounting the MGH converter is 220°C for a maximum of seconds. SN60, 62, or are the recommended types of solder. Hand soldering should not exceed 300°C for seconds per pin. The hermetically sealed metal cases are available in two different lead configuratio ns.
