These are stress ratings. Exposure of devices to any of these conditions may adversely affect
long-term reliability. Proper operation under conditions other than those listed in the Perfor-
mance/Functional Specifi cations Table is not implied.
All models are tested and specifi ed with external 1 || 10μF ceramic/tantalum output capacitors
and a 22μF external input capacitor. All capacitors are low ESR types. These capacitors are
necessary to accommodate our test equipment and may not be required to achieve specifi ed
performance in your applications. All models are stable and regulate within spec under no-load
conditions.
General conditions for Specifi cations are +25°C, V
nal” output voltage is +5V.
Input Back Ripple Current is tested and specifi ed over a 5-20MHz bandwidth. Input fi ltering is
C
Note that Maximum Power Derating curves indicate an average current at nominal input voltage.
At higher temperatures and/or lower airfl ow, the DC/DC converter will tolerate brief full current
outputs if the total RMS current over time does not exceed the derating curve.
Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3,
ground fi xed conditions, T
The On/Off Control may be driven with external logic or by applying appropriate external voltages
which are referenced to –Input Common. The On/Off Control Input should use either an open
collector/open drain transistor or logic gate which does not exceed +V
resistor to +V
Short circuit shutdown begins when the output voltage under increasing load degrades approxi-
mately 2% from the selected setting.
