HYBRID-HIGH RELIABILITY
RADIATION HARDENED
DC-DC CONVERTER
Description
The M3G-Series of DC-DC converters are radiation
hardened, high reliability converters designed for
extended operation in hostile environments. Their small
size and low weight make them ideal for applications
such as geostationary earth orbit satellites and deep
space probes. They exhibit a high tolerance to total
ionizing dose, single event effects and environmental
stresses such as temperature extremes, mechanical
shock, and vibration.
M3G
Features
n Total Dose > 200 krad(Si),
typically usable to > 300 krad(Si)
n SEE Hardened up to 82 MeV.cm2/mg
n Internal EMI filter; Converter Capable of
meeting MIL-STD-461C CE03
n Low Weight, < 110 grams
The converters incorporate a fixed frequency single
ended forward topology with magnetic feedback and
an internal EMI filter that utilizes multilayer ceramic
capacitors that are subjected to extensive lot screening
for optimum reliability. These converters are capable
of meeting the conducted emissions and conducted
susceptibility requirements of MIL-STD-461C without
any additional components. External inhibit and
synchronization input and output allow these converters
to be easily incorporated into larger power systems.
They are enclosed in a hermetic 3" x 2" x 0.475" package
constructed of an Aluminum-Silicon-Carbide (AlSiC)
base and an Alloy 48 ring frame and they weigh less
than 110 grams. The package utilizes rugged ceramic
feed-through copper core pins and is sealed using
parallel seam welding.

M3G-SERIES
(28V Input, Triple Output)
Circuit Description
An external inhibit port is provided to control converter
operation. The nominal threshold relative to the input
return (pin 2) is 1.4V. If 2.0 volts or greater are applied
to the Inhibit pin (pin 3) then the converter will
operate normally. Avoltage of 0.8V or less will cause
the converter to shut-down. The pin may be left
open for normal operation and has a nominal open
circuit voltage of 4.0V.
The M3G-Series converters utilize a single-ended
forward topology with resonant reset. The nominal
switching frequency is 500kHz. Electrical isolation
and tight output regulation are achieved through the
use of a magnetically coupled feedback. Voltage
feed-forward with duty factor limiting provides high
line rejection and protection against output over
voltage in the event of an internal control loop failure.
This mechanism limits the maximum output voltage
to approximately 20% over the nominal regardless of
the line voltage.
Synchronization input and output allow multiple
converters to operate at a common switching
frequency. Converters can be synchronized to one
another or to an externally provided clock. This can
be used to eliminate beat frequency noise or to avoid
creating noise at certain frequencies for sensitive
systems.
An internal EMI filter allows the converter to meet the
conducted emissions requirements of MIL-STD-461C
on the input power leads. A two-stage output filter
reduces the typical output ripple to less than 20mV
peak-to-peak.
The main ( +5 volt ) output is regulated by the control
loop and typically exhibits better than 1% regulation.
The auxiliary ( ±12 volt or ±15 volt ) outputs are
maintained through tight coupling in the power
transformer and main output filter inductor and
typically exhibit better than 5% regulation. The main
output and auxiliary outputs are isolated from each
other.
Design Methodology
The M3G-Series was developed using a proven
conservative design methodology which includes
selecting radiation tolerant and established reliability
components and fully derating to the requirements
of MIL-STD-975 and MIL-STD-1547 except for the
CDR type ceramic capacitors, a capacitor with 50V
rating is used for in-circuit voltage stress of less than
10V. Careful sizing of decoupling capacitors and
current limiting resistors minimizes the possibility of
photo-current burn-out. Heavy derating of the
radiation hardened power MOSFET virtually
Output power is limited under any load fault condition
to approximately 125% of rated. An overload
condition causes the converter output to behave like
a constant current source with the output voltage
dropping below nominal. The converter will resume
normal operation when the load current is reduced
below the current limit point. This protects the
converter from both overload and short circuit
conditions. The current limit point exhibits a slightly
negative temperature coefficient to reduce the
possibility of thermal runaway.
eliminates the possibility of SEGR and SEB.
A
magnetic feedback circuit is utilized instead of opto-
couplers to minimize temperature, radiation and
aging sensitivity. PSPICE and RadSPICE were used
extensively to predict and optimize circuit
performance for both beginning and end-of-life.
Thorough design analyses include Radiation
Susceptibility (TREE ), Worst Case, Stress, Thermal,
Failure Modes and Effects (FMEA) and Reliability
(MTBF).
An under-voltage lockout circuit prohibits the
converter from operating when the line voltage is too
low to maintain the output voltage. The converter will
not start until the line voltage rises to approximately
16.5 volts and will shut down when the input voltage
drops below 15.5 volts. The one volt of hysteresis
reduces the possibility of line noise interfering with
the converter’s start-up and shut down.

Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall
be guaranteed to the limits specified.

3.
Parameter verified during line and load regulation tests.
Although operation with no load is permissible, light loading on the main (+5 volt) output may cause the output
voltage of the auxiliary outputs
(±12 volt or ±15 volt) to drop out of regulation. It is therefore recommended that at least 200 mA or 20 percent
of the total output power, whichever is greater, be taken from the main (+5 volt) output.
Although operation with no load is permissible, heavy loading on the main (+5 volt) output may cause the
output voltage of the auxiliary outputs
(±12 volt or ±15 volt) to rise out of regulation. It is therefore recommended that at least 50 mA or 20 percent
of the total output power, whichever is greater, be taken from the auxiliary (±12 volt or ±15 volt) outputs.
Unless otherwise specified, “Rated” load is 20W on the main (+5 volt) output and 10 watts each on the auxiliary
(±12 volt or ±15 volt) outputs. Load currents of up to 5A and ±1A on the main and auxiliary outputs respec-
tively are acceptable as long as the total output power does not to exceed 40 watts.
Guaranteed for a D.C. to 20MHz bandwidth. Tested using a 20KHz to 10MHz bandwidth.
Capacitive load may be any value from 0 to the maximum limit without compromising dc performance.
A capacitive load in excess of the maximum limit may interfere with the proper operation of the converter’s
overload protection, causing erratic behavior during turn-on.

Application Note:
A) Attachment of the Converter
The following procedure is recommended for mounting the converter for optimum cooling and to circumvent
any potential damage to the converter.
Ensure that flatness of the plate where M3G converter to be mounted is no greater than 0.003” per linear inch.
It is recommended that a thermally conductive gasket is used to promote the thermal transfer and to fill any
voids existing between the two surfaces. IR recommends Sil-Pad 2000 with the thickness of 0.010". The
shape of the gasket should match the footprint of the converter including the mounting flanges. The gasket
is available from IR. The M3G-series converter requires either M3 or 4-40 size screws for attachment
purposes.
The procedure for mounting the converter is as follows:
1. Check the mounting surfaces and remove foreign material, burrs if any or anything that may
interfere with the attachment of the converter.
2. Place the gasket on the surface reserved for the converter and line it up with the mounting holes.
3. Place the converter on the gasket and line both up with mounting holes.
4. Install screws using appropriate washers and tighten by hand (~ 4 in·oz) in the sequence shown below.
5. Tighten the screws with an appropriate torque driver. Torque the screws up to 6 in·lb in the sequence
shown above.
