start automatically when the input voltage exceeds
the specified threshold.
6.5.3
Output Overcurrent Protection
The POL converter is protected against overcurrent
and short circuit conditions.
Upon sensing an
overcurrent condition, the POL converter will enter
hiccup mode of operation. Once the overload or
short circuit condition is removed, the POL converter
will automatically restart and Vout will return to its
nominal value.
6.5.4
Output Overvoltage Protection
The POL converter is protected against overvoltage
on the output. If the output voltage is higher than
125% of its nominal value set by the RTRIM, the high
side MOSFETS will be immediately turned off and
the low side MOSFETs will be turned on. The POL
converter will remain in the state until the output
voltage reduces below 115% of its nominal value. At
that point the POL converter will automatically
restart.

Safety
The YV09T60 POL converters do not provide
isolation from input to output. The input devices
powering YV09T60 must provide relevant isolation
requirements according to all IEC60950 based
standards. Nevertheless, if the system using the
converter needs to receive safety agency approval,
certain rules must be followed in the design of the
system.
In particular, all of the creepage and
clearance requirements of the end-use safety
requirements
must
be
observed.
These
requirements are included in UL60950 - CSA60950-
00 and EN60950, although specific applications may
have other or additional requirements.
The YV09T60 POL converters have no internal fuse.
If required, the external fuse needs to be provided to
protect the converter from catastrophic failure. Refer
to the “Input Fuse Selection for DC/DC converters”
application note on www.power-one.com for proper
selection of the input fuse. Both input traces and the
chassis ground trace (if applicable) must be capable
of conducting a current of 1.5 times the value of the
fuse without opening.
To comply with safety agencies’ requirements, a
recognized fuse must be used in series with the input
line. The fuse must not be placed in the grounded
input line. Abnormal and component failure tests
were conducted with the POL input protected by a
fast-acting 45A, 32V fuse. If a fuse rated greater
than 45A is used, additional testing may be required.
The maximum DC voltage between any two pins is
Vin under all operating conditions. In order for the
output of the YV09T60 POL converter to be
considered as SELV (Safety Extra Low Voltage),
according to all IEC60950 based standards, the input
to the POL needs to be supplied by an isolated
secondary source providing a SELV also.
