Performance/Functional Specications
Typical @ TA = +25°C under nominal line voltage, nominal output voltage, natural air convection,
external caps and full-load conditions unless noted.
All models are tested/specied with two external 0.047F output capacitors. These capacitors
are necessary to accommodate our test equipment and may not be required to achieve speci-
ed performance in your applications. All models are stable and regulate within spec under
no-load conditions.
Input Reected Ripple Current is tested/specied over a 20MHz bandwidth. Input ltering is
CIN = 33F, 100V tantalum; CBUS = 220F, 100V electrolytic; LBUS = 12H. See Technical Notes.
For consistent operation, the instantaneous input voltage for full output load must not go below
the low shutdown voltage AT ALL TIMES. Beware of excessive voltage drop from long input
wiring. For reliable startup, be sure to apply input power promptly and fully as a step function.
Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case
3, ground xed conditions, TCASE = +25°C, full load, natural air convection.
The On/Off Control may be driven with external logic or the application of appropriate voltages
(referenced to Common). The On/Off Control input should use either an open collector/open drain
transistor or logic gate which does not exceed +VIN.The On/Off Control may be supplied with with
negative logic (LO = on, HI = off) using the "N" model sufx.
Maximum Power Derating curves indicate an average current at nominal input voltage. At higher
temperatures and/or lower airow, the DC/DC converter will tolerate brief full current outputs if
the total RMS current over time does not exceed the derating curve.
All models are fully operational and meet published specications, including cold start at –40°C.
Output noise may be further reduced by adding an external lter. See I/O Filtering and Noise
Reduction.
The outputs share a common isolated return. The two output sections are not isolated from
each other.
Regulation specications describe the deviation as the line input voltage or output load current
is varied from a nominal midpoint value to either extreme.
