S-SERIES
Circuit Description
The S-Series converters utilize a single-ended
forward topology with resonant reset. The nominal
switching frequency is 525KHz. 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 enable port is provided to control
converter operation. This input is intended for
operation with an open collector transistor drive or
a relay closure to the input return. The pin may be
left open for normal operation and has a nominal
open circuit voltage of 10.5V.
Design Methodology
Output power is limited under any load fault condition
to approximately 135% for singles and 145% for
duals 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. There are no
latching elements included in the load fault protection
circuits to eliminate the possibility of falsely triggering
the protection circuits during single event radiation
exposure.
The S-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.
Heavy derating of the radiation-hardened power
MOSFET virtually 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 was 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
and Reliability (MTBF).
An under-voltage protection circuit prohibits the
converter from operating when the line voltage is
too low for safe operation. The converter will not
start until the line voltage rises to approximately 12V.

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. 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 currents 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 20MHz bandwidth. Tested using a 20KHz to 10MHz bandwidth.
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 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. Current limit point expressed as a percentage of full rated load current.
14. Total Regulation includes all combinations of line and load compared to the nominal output voltage. For dual
models all line, load, and cross regulation conditions are tested per Note 4 and Note 5.
