Output Gurrent (Note 7) Current-limited Devices can withstand sustained short circuit Input Source Impedance without damage UvQ converters must be driven from a low ac-impedance input source. The Storage Temperature 55to+125°0 DC/DCs performance and stability can be compromised by the use of highly Lead Temperature (soldering 10 sec. )+280C ductive source dances. The input circuit shown in Figure 2 is a practical solution that can be used to minimize the effects of inductance in the input Absolute maximums 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 traces. For optimum performance, components should be mounted close to in the performance /Functional Specifications Table is not implied nor recommended the dc/dc converter 1/0 Filtering, Input Ripple Current, and Output Noise (D) All models are tested and specified with 200 LFM airflow, external 1 10uF ceramic/tantalum All models in the UvQ Series are tested/specified for input ripple current (alse output capacitors. External input capacitance varies according to model type All capacitors are called input reflected ripple current) and output noise using the circuits and oW ESR types. These capacitors are necessary to accommodate our test equipment and may not be required to achieve specified performance in your applications all models are stable and layout shown in Figures 2 and 3 regulate within spec under no-load conditions General condilions for Specifications are +25"C, ViN =nominal, VoUT nominal, full load (2)Input Ripple Current is tested and specified over a 5-20MHZ bandwidth. Input filtering is Cim= 33uF tantalum, cBus= 220uF electrolytic, LBUS= 12]H OSCILLOSCOPE CURRENT (3) Note that Maximum Power Derating curves indicate an average current at nominal input voltage PROBE 3 At higher temperatures and/or lower airflow, the DC/DC converter will tolerate brief full current INPUT outputs if the total RMs current over time does not exceed the derating curve (4)Mean Time Before Failure is calculated using the Telcordia( Belcore)SR-332 Method 1, Case 3 ground fixed conditions, TPCEOARD=+25 C, full output load, natural air convection CBUS (5) 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 col- ector/open drain transistor or logic gate which does not exceed +13.5V -INPUT (6) Short circuit shutdown begins when the output voltage degrades approximately 2% from the CIN= 33uF, ESR 700mQ 100kHZ selected setting CBUS =220uF, ESR 100m2 g 100kHz 7 The outputs are not intended to sink appreciable reverse curent Sinking excessive reverse LBUS= 12HH current may damage the outputs ( 8) Output noise may be further reduced by adding an external filter See lO Filtering and Naise Reduction Figure 2. Measuring Input Ripple Current ( 9) All models are fully operational and meet published specifications, including"cold start" at-40oC Ia) 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)Overvoltage shutdown on 48V input models is not supplied in order to comply with telecom EXtemal input capacitors(CiN in Figure 2 )serve primarily as energy-storag reliabilily requirements. These requirements attempt conlinued operation despite significant elements. They should be selected for bulk capacitance (at appropriate fre (12)Do not exceed maximum power specifications when adjusting the output trim quencies), loW ESR, and high rms-ripple-current ratings. The switching nature (13) Note that the converter may operate up to +110"C with the baseplate installed. However, of DC/DC converters requires that dc voltage sources have low ac impedance thermal self-protection occurs near +110C, and there is a temperature gradient between the as highly inductive source impedance can affect system stability. In Figure 2 hotspot and the baseplate. Therefore, +100"C is recommended to avoid thermal shutdow (14) The converter is guaranteed to turn off at the UV shutdown vollage CBUs and LBus simulate a typical dc voltage bus.
