Protection Features
Input Undervoltage Lockout
Input undervoltage lockout is standard with this converter.
The converter will shut down when the input voltage drops
below a pre-determined voltage.
The input voltage must be at least 17.5V for the converter to
turn on. Once the converter has been turned on, it will shut
off when the input voltage drops below 15V. This feature is
beneficial in preventing deep discharging of batteries used in
telecom applications.
Output Overcurrent Protection (OCP)
The converter is protected against overcurrent or short
circuit conditions. Upon sensing an overcurrent condition,
the converter will switch to constant current operation and
thereby begin to reduce output voltage. When the output
voltage drops below 50% of the nominal value of output
voltage, the converter will shut down.
Once the converter has shut down, it will attempt to restart
nominally every 100 ms with a typical 1-2% duty cycle. The
attempted restart will continue indefinitely until the overload
or short circuit conditions are removed or the output voltage
rises above 50% of its nominal value.
Output Overvoltage Protection (OVP)
The converter will shut down if the output voltage across
Vout(+) (Pin 8) and Vout(-) (Pin 4) exceeds the threshold of
the OVP circuitry. The OVP circuitry contains its own
reference, independent of the output voltage regulation loop.
Once the converter has shut down, it will attempt to restart
every 100 ms until the OVP condition is removed.
Overtemperature Protection (OTP)
The converter will shut down under an overtemperature
condition to protect itself from overheating caused by
operation outside the thermal derating curves, or operation
in abnormal conditions such as system fan failure. After the
converter has cooled to a safe operating temperature, it will
automatically restart.
Safety Requirements
 The converters meet North American and International
Basic Insulation is provided between input and output. To
comply with safety agencies requirements, an input line fuse
must be used external to the converter. The table below

SQ24 Series DC-DC Converter Data Sheet
provides the recommended fuse rating for use with this
family of products.
If one input fuse is used for a group of modules, the
maximum fuse rating should not exceed 15-A (SQ modules
are UL approved with up to a 15-A fuse).
Electromagnetic Compatibility (EMC)
EMC requirements must be met at the end-product system
level,
characteristics
converters exist. However, Power-One tests its converters to
several system level standards, primary of which is the more
stringent EN55022, Information technology equipment -
Radio disturbance characteristics - Limits and methods of
measurement.
With the addition of a simple external filter (see application
notes), all versions of the SQ24 Series of converters pass
the requirements of Class B conducted emissions per
EN55022 and FCC, and meet at a minimum, Class A
radiated emissions per EN 55022 and Class B per FCC Title
47CFR, Part 15-J. Please contact di/dt Applications
Engineering for details of this testing.
Characterization
General Information
The converter has been characterized for many operational
aspects, to include thermal derating (maximum load current
as a function of ambient temperature and airflow) for vertical
and horizontal mounting, efficiency, start-up and shutdown
parameters, output ripple and noise, transient response to
load step-change, overload and short circuit.
The figures are numbered as Fig. x.y, where x indicates the
different output voltages, and y is associated with a specific
plot (y = 1 for the vertical thermal derating, …). For example,
Fig. x.1 will refer to the vertical thermal derating for all the
output voltages in general.
The following pages contain specific plots or waveforms
associated with the converter. Additional comments for
specific data are provided below.
