Q24S30033 DC-DC Converter Data Sheet
18-36 VDC Input, 3.3 VDC @ 30 A Output
Protection Features
Input Under-Voltage Lockout
Input under-voltage 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 17.5 V for the converter to
turn on. Once the converter has been turned on, it will shut
off when the input voltage drops below 15 V. This feature is
beneficial in preventing deep discharging of batteries used in
telecom applications.
Output Over-Current Protection (OCP)
The converter is protected against over-current or short cir-
cuit conditions. Upon sensing an over-current condition, the
converter will switch to constant current operation and
thereby begin to reduce output voltage. When the output
voltage drops below 1.2 Vdc, the converter will shut down
(Fig. 26).
Once the converter has shut down, it will attempt to restart
nominally every 100 ms with a 3% duty cycle (Fig 27). The
attempted restart will continue indefinitely until the overload
or short circuit conditions are removed or the output voltage
rises above 1.2 Vdc.
Output Over-Voltage 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 refer-
ence, 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.
Over-Temperature Protection (OTP)
The converter will shut down under an over-temperature
condition to protect itself from overheating caused by opera-
tion outside the thermal derating curves, or operation in ab-
normal conditions such as system fan failure. After the con-
verter has cooled to a safe operating temperature, it will
automatically restart.
Safety Requirements
The converters meet North American and International
safety regulatory requirements per UL60950 and EN60950.
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. A 10-A fuse is
recommended for use with this product.
Electromagnetic Compatibility (EMC)
EMC requirements must be met at the end-product system
level, as no specific standards dedicated to EMC character-
istics of board mounted component dc-dc converters exist.
However, di/dt tests its converters to several system level
standards, primary of which is the more stringent EN55022,
Information technology equipment - Radio disturbance char-
acteristics - Limits and methods of measurement.
With the addition of a simple external filter (see application
notes), all versions of the Q24S30 converters pass the re-
quirements of Class B conducted emissions per EN55022
and FCC, and meet at a minimum, Class A radiated emis-
sions per EN 55022 and Class B per FCC Title 47CFR, Part
15-J. Please contact di/dt Applications Engineering for de-
tails of this testing.
