Performance Specifications and Ordering Guide ➀
Caution: This product is not internally fused. To comply with safety agency certifications and to avoid injury to personnel or equipment, the user must supply an external fast-blow fuse to the input terminals.
(1) All models are tested and specified with external 1||10 µF ceramic/tantalum output capacitors no external input capacitor. All capacitors are low ESR types. These capacitors are necessary to accom-
(2) Input Ripple Current is tested and specified over a 5 Hz to 20 MHz bandwidth. Input filtering is C
(3) Note that Maximum Power Derating curves indicate an average current at nominal input voltage. At higher temperatures and/or lower airflow, the DC/DC converter will tolerate brief full current outputs if
(4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground fixed conditions, Tpcboard = +25 deg.C, full output load, natural air convection.
(5) The On/Off Control is normally controlled by a switch or open collector or open drain transistor. But it may also be driven with external logic or by applying appropriate external voltages which are
(6) Short circuit shutdown begins when the output voltage degrades approximately 2% from the selected setting.
(7) The outputs are not intended to sink appreciable reverse current. This may damage the outputs.
(8) Output noise may be further reduced by adding an external filter. See I/O Filtering and Noise Reduction.
(9) All models are fully operational and meet published specifications, including “cold start” at –40 C.
(10) Regulation specifications describe the deviation as the line input voltage or output load current is varied from a nominal midpoint value to either extreme.
(11) Output accuracy is dependent on user-supplied trim resistors. To achieve high accuracy, use ±1% or better tolerance metal-film resistors mounted close to the converter.
(12) Output current limit and short circuit protection is non-latching. When the overcurrent fault is removed, the converter will immediately recover.
(13) Do not exceed maximum power specifications when adjusting the output trim.
(14) At zero output current, the output may contain low frequency components which exceed the ripple specification. The output may be operated indefinitely with no load.
(15) Input Fusing: If reverse polarity is accidentally applied to the input, a body diode will become forward biased and will conduct considerable current. To ensure reverse input protection with full output load,
(16) “Hiccup” overcurrent operation repeatedly attempts to restart the converter with a brief, full-current output. If the overcurrent condition still exists, the restart current will be removed and then tried again.
