DESCRIPTION
a TTL low voltage (0.8 V or less) to the inhibit terminal (pin 1)
disables the output. Leaving the inhibit terminal unconnected or
connecting the inhibit terminal to an open collector gate enables the
output. The inhibit terminal has an open circuit voltage of 9 to 11 V.
In the inhibit mode the inhibit pin will source a maximum of 4 mA.
See “Inhibit Interface,” Figure 2.
The MGA Series™ of DC/DC converters delivers 5 watts of output
power from a wide input voltage range of 16 to 40 VDC with up to
74% efficiency. Output models of 5, 12, 15, ±5, ±12 and ±15 VDC
meet a variety of system needs. All units withstand transients of up
to 50 V for up to 50 milliseconds and operate over the full military
temperature range of -55°C to +125°C.
MIL-STD-461
CONVERTER DESIGN
Use Interpoint’s FMGA-461 EMI filter to pass the CE03 require-
ments of MIL-STD-461C.
The MGA converters incorporate flyback topology with a typical
constant switching frequency of 500 kHz. 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. The feed-forward compensation design delivers an audio
rejection of 50 dB, typical, with input ripple as low as 50 mA p-p and
output ripple as low as 100 mV p-p. Output filter examples in Figures
3 and 4 provide suggested solutions for systems where very low
output ripple is required.
SURFACE MOUNT PACKAGE
The MGA 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).
Internal components are soldered with SN96 (melting temperature
221°C) to prevent damage during reflow. Maximum reflow tempera-
ture for surface mounting the MGA 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.
Tightly coupled magnetics minimize cross regulation in the MGA
dual output models. Either output can provide up to 80% of the total
available output power, providing the opposite output is carrying at
least 20% of the total output power.
The converter’s short circuit current protection restricts the output
current to approximately 115% of the full load output current.
The hermetically sealed metal cases are available in two different
lead configurations. See Section B8, cases D1 and D2.
INHIBIT FUNCTION
The MGA converter’s inhibit terminal disables internal switching,
resulting in no output and very low quiescent input current. Applying

Notes
1. Up to 4 watts, 80% of the total output power is available from either output
providing the opposite output is simultaneously carrying 20% of the total
output power. Each output must carry a minimum of 20% of the total output
power in order to maintain regulation on the negative output.
2. Applies to both +Vout and –Vout
3. Cross regulation is specified for the following percentages of total output
power: +PO = 20% and –PO = 80% to +PO =80% and –PO = 20%
4. Indefinite short circuit protection not guaranteed above 125°C (case).
5. Load transient transition time is >10 µs.
6. Response of either output when the load for each output is simultaneously
transitioned from 25% to 50% to 25% of total output power (5 watts).
7. Recovery time is measured from application of the transient to the point at
which Vout is within regulation.
8. Input step transition time is >10µs.

Maximum reflow temperature is 220°C for a
maximum of 30 seconds. SN60, SN62, or SN63
are the recommended types of solder. See below
for Solder Mask instructions.

1. Pad dimensions are for the solder mask opening. Lead common to
each other can be connected underneath as desired.
2. Ground pins should be connected to the center pad for improved
grounding.
0.030 (0.76)
3. Center pad should not have a solder mask. Solder, copper, or Au/Ni
plate are preferred over solder for adhesive attach.
4. Solder coat to solder down converter.
5. If less rotation of case is desired, make the pad width 0.020inches
(0.51 mm). Pad length can be extended 0.010 inches (0.25 mm)
towards the case body and as-desired dimension away from the case
body.
6. Do not exceed 220°C as measured on the body of the converter (top
or bottom).
7. Attach the body of the case to the board with a thermally conductive
adhesive or SN60, 62, or 63 solder. The adhesive can be electrically
conductive as well. It can be applied as an underfill post solder or
dispensed and cured prior or during solder.
