M3L-SERIES
+28V Input, Single/Dual Output
HYBRID-HIGH RELIABILITY
RADIATION TOLERANT
DC-DC CONVERTER
Description
The M3L-Series of DC-DC converters are radiation tolerant,
high reliability devices designed for moderate radiation
environments such as those encountered by low earth orbit
satellites and launch vehicles. For higher radiation
environments, the M3G-Series of DC-DC converters is
recommended. Features include small size, low weight and
a high tolerance to total ionizing dose, single event effects
and environmental stresses such as temperature extremes,
mechanical shock, and vibration. All components are fully
de-rated to meet the requirements of MIL-STD-975 and MIL
-STD-1547 and GSFC PPL-21 Appendix B. Extensive
documentation including Radiation Susceptibility, Thermal
Analysis, Stress Analysis and MTBF are available.

M3L-SERIES
(+28V Input, Single/Dual Output)
Circuit Description
The M3L-Series converters utilize a single-ended forward
topology with resonant reset. The nominal switching fre-
quency is 500 kHz. 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.
An external inhibit port is provided to control converter
operation. The converter’s operation is inhibited when
this pin is pulled low. It is intended to be driven by an
open collector logic device. The pin may be left open for
normal operation and has a nominal open circuit voltage
of 10.5V with respect to the input return (pin 2).
An internal EMI filter allows the converter to meet the
conducted emissions requirements of MIL-STD-461C on
the input power leads. A single-stage output filter reduces
the typical output ripple to less than 50mV peak-to-peak.
The output voltage of all models can be adjusted using a
single external resistor.
Design Methodology
Output current is limited under any load fault condition to
approximately 125% of rated. An overload condition caus-
es 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.
The M3L-Series was developed using a proven
conservative design methodology which includes
selecting radiation tolerance and established reliability
components and fully de-rating to the requirements of
MIL-STD-975 and MIL-STD-1547. Heavy de-rating of
the power MOSFET gate and drain voltages minimize the
possibility of SEGR and SEB. A magnetic feedback
circuit is utilized instead of opto-couplers to minimize
temperature, radiation and aging sensitivity. PSPICE was
used extensively to predict and optimize circuit
performance for both beginning and end-of-life.
Thorough design analyses include Radiation
Susceptibility (TREE), Stress, Thermal, and Reliability
(MTBF).

Notes: Electrical Performance Characteristics Table
1. Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall be guaranteed to the limits
specified.
2. Parameter verified during line and load regulation tests.
3. Output load current must be distributed such that at least 20% of the total load current is being provided by one of the outputs.
4. Load current split equally between outputs on dual output models.
5. 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.
6. Guaranteed for a D.C. to 20 MHz bandwidth. Tested using a 20 kHz to 10 MHz bandwidth using the circuit shown below.
7. 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.
8. Overload power dissipation is defined as the device power dissipation with the load set such that VOUT = 90% of nominal.
9. Load step transition time 10 s.
10. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of its steady state value
11. Line step transition time 100 s.
12. 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 4)
to the point where VOUT = 90% of nominal.
13. For operation at temperatures between +85°C and +125°C, de-rate the maximum output power linearly from 100% to 75%.
