MCH SERIES™ SINGLE & DUAL
DC/DC CONVERTERS
With a miniature footprint of just 0.8 square inches, the MCH
Series™ 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, aero-
space, 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 oper-
ations. 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.
MIL-STD-461
Use Interpoint’s FMSA-461 EMI filter to pass the CE03 requirements
of MIL-STD-461C.
CONVENIENT PACKAGING
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.)
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 SERIES™ SINGLE & DUAL
DC/DC CONVERTERS
PROTECTION FEATURES
The MGH Series™ 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 mili-
tary, 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.
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 oper-
ations. 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 approx-
imately 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.
SURFACE MOUNT PACKAGE
MGH DC/DC converters can be surface 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).
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.
Internal components are soldered with SN96 (melting temperature
221°C) to prevent damage during reflow. Maximum reflow tempera-
ture for surface mounting the MGH converter is 220°C for a
maximum of 30 seconds. SN60, 62, or 63 are the recommended
types of solder. Hand soldering should not exceed 300°C 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 μH.
6. Transition ≥ 10 μs. 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.
4. Maximum duration of short circuit: 25°C-– 90 seconds, 125°C – 30 seconds.
5. Load fault is a short circuit (<50 mohms). Recovery is into resistive full load,
with one output shorted at a time.
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%.
