If the shutdown pin is to be connected to a long wire, it is recommended that a Since the design uses no large electrolytic capacitors, any use of a lower capacitor decouples the pin to the supply common in order to avoid the risk of frequency must allow for the effects of increased ripple. Additional external injecting noise into the converter circuit. A series resistor may also be helpful. filtering may be required. Values of 10nF and 1kΩ may be used. Many NPH series converters may be switched together simply by linking the primary control pins. The primary common pins must also be linked. www.murata-ps.com/support KDC_NPH10SC.J05 Page 3 of 8

NPH10S Series Isolated 10W Single Output DC-DC Converters APPLICATION NOTES (continued) SYNCHRONISATION The converter frequency may be synchronised to an external frequency by connecting a negative going pulse to the SS pin. The drive signal is typically 8V to 12V amplitude and 100ns to 200ns duration. A suitable circuit consists of a CMOS timer (TLC555) connected as an oscillator or as a pulse shaper. Its logic output (not the discharge output) should be connected via a 4.7nF capacitor to the converter pin. The synchronised frequency is above the free running value. However, the free running frequency can be lowered, so that synchronisation may include frequencies near or below the natural value. An example of a practical circuit is shown below, which uses a zener diode to lower the natural frequency. Several converters of this family may be synchronised from the same reference provided the waveform can be maintained by the use of an adequate driver circuit. If the rise time is more than 20ns, for example, synchronisation may not be achieved over the specified frequency range. For best efficiency, set the frequency within the specified range of its natural state.

Murata Power Solutions NPH10S series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 1500V DC for 1 second. A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?” The NPH10S series has been recognized by Underwriters Laboratory, both input and output should normally be maintained within SELV limits i.e. less than 42.4V peak, or 60VDC. The isolation test voltage represents a measure of immunity to transient voltages and the part should never be used as an element of a safety isolation system. The part could be expected to function correctly with several hundred volts offset applied continuously across the isolation barrier; but then the circuitry on both sides of the barrier must be regarded as operating at an unsafe voltage and further isolation/insulation systems must form a barrier between these circuits and any user-accessible circuitry according to safety standard requirements. REPEATED HIGH-VOLTAGE ISOLATION TESTING It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on materi- als, construction and environment. While manufactured parts can withstand several times the stated test voltage, the isolation capability does depend on the wire insulation. Any material, including this enamel (typically polyurethane) is susceptible to eventual chemical degradation when subject to very high applied voltages thus implying that the number of tests should be strictly limited. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be reduced by 20% from specified test voltage. www.murata-ps.com/support KDC_NPH10SC.J05 Page 4 of 8

NPH10S Series Isolated 10W Single Output DC-DC Converters EMC FILTERING AND SPECTRA FILTERING The module includes a basic level of filtering, sufficient for many applications. 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 a capacitor 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 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 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. Radiated noise is present in magnetic and electrostatic forms. The latter is suppressed by the metal case, which is connected to the output return, typically a zero-volt point. Thanks to the small size of these units, neither form of noise will be radiated “efficiently”, so will not normally cause a problem. Any question of this kind usually better repays attention to conducted signals.
