8.3 Feature Description
8.3.1 Isolation
Underwriters Laboratories, UL™ defines several classes of isolation that are used in modern power supplies.
Safety extra low voltage (SELV) is defined by UL (UL1950 E199929) as a secondary circuit which is so
designated and protected that under normal and single fault conditions the voltage between any two accessible
parts, or between an accessible part and the equipment earthing terminal for operational isolation does not
exceed steady state 42 V peak or 60 VDC for more than 1 second.
8.3.1.1 Operation or Functional Isolation
Operational or functional isolation is defined by the use of a high-potential (hipot) test only. Typically, this
isolation is defined as the use of insulated wire in the construction of the transformer as the primary isolation
barrier. The hipot one-second duration test (dielectric voltage, withstand test) is a production test used to verify
that the isolation barrier is functioning. Products with operational isolation should never be used as an element in
a safety-isolation system.
8.3.1.2 Basic or Enhanced Isolation
Basic or enhanced isolation is defined by specified creepage and clearance limits between the primary and
secondary circuits of the power supply. Basic isolation is the use of an isolation barrier in addition to the insulated
wire in the construction of the transformer. Input and output circuits must also be physically separated by
specified distances.
8.3.1.3 Continuous Voltage
For a device that has no specific safety agency approvals (operational isolation), the continuous voltage that can
be applied across the part in normal operation is less than 42.4 VRMS, or 60 VDC. Ensure that both input and
output voltages maintain normal SELV limits. The isolation test voltage represents a measure of immunity to
transient voltages.
WARNING
Do not use the device as an element of a safety isolation system when SELV is
exceeded
If the device is expected to function correctly with more than 42.4 VRMS or 60 VDC applied continuously across the
isolation barrier, then the circuitry on both sides of the barrier must be regarded as operating at an unsafe
voltage, and further isolation or insulation systems must form a barrier between these circuits and any user-
accessible circuitry according to safety standard requirements.
8.3.1.4 Isolation Voltage
Hipot test, flash-tested, withstand voltage, proof voltage, dielectric withstand voltage, and 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. TI’s DCP02 series of dc-dc
converters are all 100% production tested at 1.0 kVAC for one second.
8.3.1.5 Repeated High-Voltage Isolation Testing
Repeated high-voltage isolation testing of a barrier component can degrade the isolation capability, depending on
materials, construction, and environment. The DCP02 series of dc-dc converters have toroidal, enameled, wire
isolation transformers with no additional insulation between the primary and secondary windings. While a device
can be expected to withstand several times the stated test voltage, the isolation capability depends on the wire
insulation. Any material, including this enamel (typically polyurethane), is susceptible to eventual chemical
degradation when subject to very-high applied voltages. Therefore, strictly limit the number of high-voltage tests
and repeated high-voltage isolation testing. However, if it is absolutely required, reduce the voltage by 20% from
specified test voltage with a duration limit of one second per test.
