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 derated 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
Circuit Description
The M3L-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 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).
The output voltage of all models can be adjusted
using a single external resistor.
Design Methodology
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 M3L-Series was developed using a proven
conservative design methodology which includes
selecting radiation tolerance and established
reliability components and fully derating to the
requirements of MIL-STD-975 and MIL-STD-1547.
Heavy derating 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 ).
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.

Notes. Electrical Performance Characteristics
1)
Parameter is tested as part of design characterization or after design changes. Thereafter, parameter shall be guaranteed to the
limits specified.
2)
3)
4)
5)
Parameter verified during line and load regulation tests.
Output load current must be distributed such that at least 20% of the total load current is being provided by one of the outputs.
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.
6)
7)
Guaranteed for a D.C. to 20MHz bandwidth. Tested using a 20KHz to 10MHz bandwidth using the circuit shown below.
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)
9)
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.
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 µs.
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, derate the maximum output power linearly from 100% to 75%.
