PRODUCT OVERVIEW
The CRE1 series are a cost effective 1W DC-DC
converter series, in industry standard packages
with industry standard pinout. Popular input
and output voltages are available. The galvanic
isolation allows the device to be configured to
provide an isolated negative rail in systems where
only positive rails exist. The wide temperature
range guarantees startup from –40°C and full 1
watt output at 85°C3.

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 CRE1 series of DC-DC converters are all 100% production tested at their stated isolation voltage. This is 1kVDC for 1 second for C versions and 3kVDC for
1 second for 3C versions.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
The CRE1 series, through hole variants (excluding surface mount variants) have been recognised by Underwriters Laboratory for functional insulation, 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 materials,
construction and environment. The CRE1 series has toroidal isolation transformers, with no additional insulation between primary and secondary windings of enamelled 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 20% 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 CRE1 series has been recognised by Underwriters Laboratory (UL) to UL60950 for functional insulation in a maximum still air ambient temperature of 100°C for the C versions
and 130°C for the 3C versions as measured on the case of the unit (hotspot). The CRE1S0505MC is not currently UL recognised.
The CRE1 series of converters are not internally fused so to meet the requirements of UL60950 an anti-surge input line fuse should always be used with ratings as defined below.
CRE1S03xxS3C: 1A
CRE1S05xxxxC: 0.7A
CRE1S12xxSC: 0.2A
CRE1S24xxSC: 0.16A
All fuses should be UL recognised, 125V rated.
File number E151252 applies.

APPLICATION NOTES
Minimum load
The minimum load to meet datasheet specification is 10% of the full rated load across the specified input voltage range. Lower than 10% minimum loading will result in
an increase in output voltage, which may rise to typically double the specified output voltage if the output load falls to less than 5%.
Capacitive loading and start up
Typical start up times for this series, with a typical input voltage rise time of 2.2µs and output capacitance of 10µF, are shown in the table below. The product
series will start into a capacitance of 47µF with an increased start time, however, the maximum recommended output capacitance is 10µF.

Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test configuration.
C1 1µF X7R m ultilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC-DC converter
C2 10µF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC-DC converter with an ESR of less
than 100mΩ at 100 kHz
C3 100nF multilayer ceramic capacitor, general purpose
R1 450Ω resistor, carbon film, ±1% tolerance
R2 50Ω BNC termination
T1 3T of the coax cable through a ferrite toroid
RLOAD Resistive load to the maximum power rating of the DC-DC converter. Connections should be made via twisted wires
Measured values are multiplied by 10 to obtain the specified values.
Differential Mode Noise Test Schematic
Output Ripple Reduction
By using the values of inductance and capacitance stated, the output ripple at the rated load is lowered to 5mV p-p max.
Component selection
Capacitor: It is required that the ESR (Equivalent Series Resistance) should be as low as possible, ceramic types are recommended.
The voltage rating should be at least twice (except for 15V output), the rated output voltage of the DC-DC converter.
Inductor: The rated current of the inductor should not be less than that of the output of the DC-DC converter. At the rated current, the DC resistance of the inductor
should be such that the voltage drop across the inductor is <2% of the rated voltage of the DC-DC converter. The SRF (Self Resonant Frequency) should be
>20MHz.
