(With Derating)
All models are tested and specifi ed with external 1 || 10uF ceramic/tantalum output capacitors and external
22uF 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, VIN = nominal, VOUT = nominal, full load.
Input Ripple Current is tested and specifi ed over a 5 Hz to 20 MHz bandwidth. Input fi ltering is CIN = 33μF/100V
tantalum, CBUS = 220μF/100V electrolytic, LBUS = 12μH.
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. All Derating curves are presented at sea level altitude. Be
aware of reduced power dissipation with increasing density altitude.
Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground fi xed
conditions, TPCBOARD = +25°C, full output load, natural air convection.
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 +13.5V.
Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected setting.
The outputs are not intended to sink appreciable reverse current.
Output noise may be further reduced by adding an external fi lter. See I/O Filtering and Noise Reduction.
All models are fully operational and meet published specifi cations, including “cold start” at –40°C.

thermal self-protection occurs near +125°C and there is a temperature gradient from high power components.
Therefore, +100°C baseplate temperature is recommended to avoid thermal shutdown.
