With an ultra wide input voltage range of 16-160VDC, the RUW series is capable of withstanding surges from 24,36,48,72, 90 and 110V systems, largely eliminating the requirement for input protection circuitry. Optional features include a Power Fail/DC OK signal and circuitry to facilitate long hold-up times with a small external capacitor across ±Vint pins.

The RUW15 series of converters are not internally fused so to meet the requirements of UL a 3A anti-surge input line fuse should always be used. File number E151252 applies. RoHS COMPLIANCE INFORMATION This series is compatible with RoHS soldering systems with a peak wave solder temperature of 260ºC for 10 seconds. The pin termination finish on this product series is a Gold flash (0.05-0.10 micron) over Nickel Preplate. The series is backward compatible with Sn/Pb soldering systems. Tinned tabs are provided along the case edges to provide mechanical support through slots in the PCB. Hand soldering of these tabs may be necessary to ensure satisfactory joint quality. For further information, please visit www.murata-ps.com/rohs APPLICATION NOTES The RUW15 can be used as a general purpose wide input DC/DC converter simply with the addition of the recommended input capacitor, low ESR type 10uF. Output Capacitors The RUW series does not require output capacitors to meet datasheet specification. To meet datasheet specifications, total output capacitance should not exceed: Output Voltage (V) 5 12 24 Max. Recommended Output Capacitance (µF) 1000 470 220 Remote ON/OFF control The remote ON/OFF input to the RUW15 converter is referenced to the primary ground and when pulled below 0.5V, the RUW15 will not operate. The RUW15 will be operational if the pin is left open. In noisy environments, it is recommended to decouple the remote ON/OFF pin to ground with a 10nF capacitor. Hold-up If hold-up of the output is required on input drop-outs such as occur on battery changeovers, the RUW15 has an optional hold-up feature (-H versions) which maintains the output if the input voltage falls to zero. The hold-up time can be set by the connection of an external capacitor across the –Vint and +Vint pins. The hold-up time is independent of the input voltage applied before drop-out Configuration for extended hold-up time This capacitor is charged by the RUW15 to around 80 V and is internally switched into the RUW15 input upon input voltage failure. An internal diode prevents this high voltage appearing on the RUW15 input pins. The capacitor is referenced to the input ground of the RUW15 and therefore should have appropriate isolation clearance to the RUW15 output circuitry. As drop-outs are not expected to occur in quick succession, the capacitor is allowed to recharge slowly over about one minute before full hold-up is again available. This helps to minimise internal stresses in the RUW15 converter. As an example, EN50155 requirement to maintain output for 30 ms on supply change-over (Class C2) is met with a capacitor of 220 uF rated at 100 V for any nominal input voltage up to 110 VDC with the RUW15 operating at maximum load. The benefit conferred by the hold-up option is most evident when hold-up from low nominal voltages is required even if the wide input range of the RUW15 is not needed. In the above example to achieve 30 ms holdup with a capacitor across the input in a 24V nominal system, an expensive and large capacitor of 3900uF would be required rated at higher than the maximum input voltage. The below graph shows values of capacitance against hold-up time for 15W loading. At lighter loads the hold-up time increases proportionally. In some applications the external capacitor could be made up from parallel multilayer ceramic parts which would dramatically improve lifetime compared with alternative electrolytic types. 70 60 50 ms 40 5v 12v 30 24v 20 10 0 0 50 100 150 200 250 300 µF www.murata-ps.com/support KDC_RUW15.B02 Page 3 of 13 RUW15 Series Isolated Ultra-Wide Input DC/DC Converters APPLICATION NOTES (continued) Power Fail Warning Details A ‘power fail’ signal is available which goes active after the input voltage drops out but before the output loses regulation. Over-temperature and over-voltage monitoring is included which also activates the ‘power fail’ signal.The signal goes active if the output voltage exceeds approximately 15 % of nominal, if the output is grossly less than nominal such as under short circuit conditions or if the case temperature exceeds approximately 120 degrees C. The signal is an open pnp emitter output which goes to a low voltage, typically less than 1V when active, signifying a fault. The signal goes active some milliseconds before the output drops after the converter input drops to zero, effectively giving a power fail warning. The actual value of warning time is defined by the hold-up capacitance added as shown below. The signal can sink 50 mA and withstand 30 V in the inactive condition. The signal is referenced to RUW15 -Vout and typically is pulled to a system rail with a 10K resistor. The open emitter arrangement allows the RUW15 to actively sink current into the Power Fail output even if the RUW15 is unpowered or short circuited, correctly indicating a fault condition.

This standard defines a range of nominal battery voltages that may be encountered with possible fluctuations and interruptions. Nominal voltages (Un) are 24V, 48V, 72V, 96V and 110VDC with tolerances of -30/+25%. Fluctuations can take the nominal voltages up +40% for one second and down -40% for 100ms. The possible total range of nominals and fluctuations is therefore 14.4V to 154V (24V -40% to 110V +40%). Other national variations include US rail nominal battery voltages of 37V and 74V; higher surges of 1.5 x Un for one second and 3.5 x Un for 20ms found in the UK standard RIA12 and lower dips to 12V for 100ms found in the French standard NF F 01-510. Figure 1 summarises this. The ranges of voltages for the French standard NF F 01-510 and for the USA are also shown for information. Additionally, according to EN 50155, complete interruptions of the supply can last for up to 10ms (Class S2) or 30ms during supply changeover (Class C2).

Where lower noise levels are desired, filters can easily be added to achieve any required noise performance. A DC/DC converter generates noise in two principle forms: that which is radiated from its body and that conducted on its external connections. There are three separate modes of conducted noise: input differential, output differential and input-output. This last appears as common mode at the input and the output, and cannot therefore be removed by filtering at the input or output alone. The first level of filtering is to connect capacitors between input and output returns, to reduce this form of noise. It typically contains high harmonics of the switching frequency, which tend to appear as spikes on surrounding circuits. The voltage rating of this capacitor must match the required isolation voltage. (Due to the great variety in isolation voltage and required noise performance, this capacitor has not been included within the converter.) Input ripple is a voltage developed across the internal Input decoupling capacitor. It is therefore measured with a defined supply source impedance. Although simple series inductance will provide filtering, on its own it can degrade the converter stability. A shunt capacitor is therefore recommended across the converter input terminals, so that it is fed from a low impedance. If no filtering is required, the inductance of long supply wiring could also cause a problem, requiring an input decoupling capacitor for stability. An electrolytic type will perform well in these situations. The input-output filtering is performed by the common-mode choke on the primary. This could be placed on the output, but would then degrade the regulation and produce less benefit for a given size, cost, and power loss. The metallic case of the product is connected internally to output 0V and as such also has reinforced isolation to the input. Tinned tabs on the casing may be soldered to PCB slots to provide mechanical support and extra electrical connection to the casing to optimise EMC shielding. Rail standard EN50155 references EN50121-3-2 for conducted EMI which is less severe than EN55011 so the RUW15 also meets these levels comfortably. The RUW15 has been evaluated to meet the requirements of EN55011 curve B with an external filter as shown. The limit line shown is quasi peak curve B.
