PD-94534Q M3G-SERIES HYBRID - HIGH RELIABILITY RADIATION HARDENED DC-DC CONVERTER 28V Input, Single/Dual Output 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. 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. Manufactured in a facility fully qualified to MIL-PRF38534, these converters are fabricated utilizing DLA Land and Maritime qualified processes. For available screening options, refer to device screening table in the data sheet. Non-flight versions of the M3G-Series converters are available for system development purposes. Variations in electrical specifications and screening to meet custom requirements can be accommodated. www.irf.com M3G Features n Total Dose > 200 KRad(Si), typically usable to > 300 KRad(Si) n SEE Hardened to LET up to 82 MeV.cm2/mg n Internal EMI filter; Converter Capable of meeting MIL-STD-461C CE03 n Low Weight, < 110 grams n Magnetically Coupled Feedback n 18V to 50V DC Input Range n Up to 40W Output Power n Single and Dual Output Models Include 3.3, 5, 5.2, 12, 15, ±5, ±7, ±12 and ±15V n High Efficiency - to 82% n -55°C to +125°C Operating Temperature Range n 100MΩ @ 500VDC Isolation n Under-Voltage Lockout n Short Circuit and Overload Protection n Remote Sense on Single Output Models n Adjustable Output Voltage for Duals n Synchronization Input and Output n Output Over Voltage Limiter n External Inhibit n > 5,000,000 Hour MTBF n Standard Microcircuit Drawings Available Applications n n n Geostationary Earth Orbit Satellites (GEO) Deep Space Satellites / Probes Strategic Weapons and Communication System 1 09/11/12 M3G-SERIES (28V Input, Single/Dual Output) Circuit Description 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. 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. Output current 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. 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. 2 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. A voltage 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. 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. Remote sense is provided on the single output models to compensate for voltage drops in the interconnects between the converter and the load. The output voltage of dual output models can be adjusted by a single external resistor. 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 eliminates the possibility of SEGR and SEB. A magnetic feedback circuit is utilized instead of optocouplers 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). www.irf.com M3G-SERIES (28V Input, Single/Dual Output) Specifications Absolute Maximum Ratings Recommended Operating Conditions Input voltage range Output power Lead temperature Operating temperature Storage temperature Input voltage range -0.5Vdc to +80Vdc Internally limited +300°C for 10 seconds -55°C to +135°C -55°C to +135°C +18Vdc to +60Vdc +18Vdc to +50Vdc 0 to Max.

Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall be guaranteed to the limits specified. Parameter verified during line and load regulation tests. Limit represents 80% of total rated output current. To achieve rated output power, the remaining 20% of the total rated output current must be provided by the other output. Load current split equally between outputs on dual output models. Cross regulation is measured with 20% rated load on output under test while changing the load on the other output from 20% to 80% of rated. 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. Overload power dissipation is defined as the device power dissipation with the load set such that VOUT = 90% of nominal. Load step transition time ≥ 10 µs. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of its steady state value. Line step transition time ≥ 100 µs. Turn-on delay time from either a step application of input power or a logic low to a logic high transition on the inhibit pin (pin 3) to the point where VOUT = 90% of nominal. Although operation at temperatures between +85°C and +125°C is guaranteed, no parametric limits are specified. www.irf.com 5 M3G-SERIES (28V Input, Single/Dual Output) Fig 1.

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. 2. 3. 4. Check the mounting surfaces and remove foreign material, burrs if any or anything that may interfere with the attachment of the converter. Place the gasket on the surface reserved for the converter and line it up with the mounting holes. Place the converter on the gasket and line both up with mounting holes. 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. 10 www.irf.com M3G-SERIES (28V Input, Single/Dual Output) B) Output Voltage Adjustment.
