PRODUCT OVERVIEW

The NDS6 series of DC/DC converters offer single

and dual output voltages from an input voltage

range of 18-36V. The NDS6 is housed in an indus-

try standard package with a standard pinout. The

NDS6 is packaged in a metal case for improved

EMI shielding and is also encapsulated for supe-

rior thermal performance. Versions with optional

remote on/off control pin are also available.

APPLICATION NOTES

Control Pin

NDS6D Cross Regulation

This provides an OFF function, which puts the converter into a low

power mode, when the voltage applied to the pin is less than ꢀ.8V.

When the pin is high or un-connected, the converter is on.

Load regulation is at its best when the positive and negative loads are balanced. When the loads

are asymmetric, the negative output is not as tightly regulated as the positive output. To meet

datasheet speciﬁcation, a minimum load of 1ꢀ0 of output load current is required on each output.

The NDS6D can be used with much lighter loading but the negative output voltage may rise above

maximum datasheet speciﬁcation.

Output Capacitors

The NDS6 series does not require output capacitors to meet datasheet speciﬁcation. To meet datasheet speciﬁcation, output capacitance should not exceed:

TECHNICAL NOTES

ISOLATION VOLTAGE

‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test voltage,

applied for a speciﬁed time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.

Murata Power Solutions NDS6 series of DC/DC converters are all 1ꢀꢀ0 production tested at their stated isolation voltage. This is 1.±kVDC for 1 second.

A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”

The NDS6 has been recognized by Underwriters Laboratory for functional isolation. Both input and output should normally be maintained within SELV limits i.e. less than 42.4V

peak, or 6ꢀVDC. 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 materials,

construction and environment. The NDS6 series has an ER ferrite core, with no additional insulation between primary and secondary windings of enameled wire. While parts can be

expected to 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 2ꢀ0 from speciﬁed test voltage.

This consideration equally applies to agency recognized parts rated for better than functional isolation where the wire enamel insulation is always supplemented by a further

insulation system of physical spacing or barriers.

SAFETY APPROVAL

The NDS6 series has been recognised by Underwriters Laboratory (UL) to UL 6ꢀ9±ꢀ for functional insulation in a maximum ambient temperature of 8±ºC and/or case temperature

limit of 12ꢀºC (case temperature measured on the face opposite the pins). File number E1±12±2 applies.

Note: This series gained UL 6ꢀ9±ꢀ recognition for products manufactured on or after datecode G1148, any NDS6 parts manufactured before this date code should not be consid-

ered UL 6ꢀ9±ꢀ recognized. Any NDS6 that is UL recognized will be printed with the UL logo.

RoHS COMPLIANCE INFORMATION

This series is compatible with RoHS soldering systems with a peak wave solder temperature of 26ꢀºC for 1ꢀ seconds. The pin termination ﬁnish

on this product series is a Gold ﬂash (ꢀ.ꢀ±-ꢀ.1ꢀ micron) over Nickel Preplate. The series is backward compatible with Sn/Pb soldering systems.
