ASQ24 DC-DC Converter Series Data Sheet
18 to 36 VDC Input; 1.0 to 12 VDC Output
Protection Features
Input Undervoltage Lockout
provides the recommended fuse rating for use with this fami-
ly of products.
Input undervoltage lockout is standard with this converter.
The converter will shut down when the input voltage drops
below a pre-determined voltage.
Output Voltage
3.3V
12V - 5.0V, 2.5V
2.0V - 1.0V
Fuse Rating
8A
6A
4A
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 cir-
cuit conditions. Upon sensing an overcurrent condition, the
converter will switch to constant current operation and there-
by 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 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.
Overtemperature Protection (OTP)
The converter will shut down under an overtemperature con-
dition to protect itself from overheating caused by operation
outside the thermal derating curves, or operation in abnor-
mal conditions such as system fan failure. After the conver-
ter has cooled to a safe operating temperature, it will auto-
matically restart.
Safety Requirements
? The converters meet North American and International
safety regulatory requirements per UL 60950-1/CSA 22.2
No. 60950-1-07 Second Edition, IEC 60950-1: 2005, and
EN 60950-1:2006. 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
If one input fuse is used for a group of modules, the maxi-
mum fuse rating should not exceed 15-A (ASQ 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, as no specific standards dedicated to EMC characte-
ristics of board mounted component dc-dc 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 distur-
bance characteristics - Limits and methods of measurement.
With the addition of a simple external filter (see application
notes), all versions of the ASQ24 Series of converters pass
the requirements of Class B conducted emissions per
EN55022 and FCC, and meet at a minimum, Class A ra-
diated emissions per EN 55022 and Class B per FCC Title
47CFR, Part 15-J. Please contact di/dt Applications Engi-
neering 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 as-
sociated with the converter. Additional comments for specific
data are provided below.
Test Conditions
All data presented were taken with the converter soldered to
a test board, specifically a 0.060” thick printed wiring board
(PWB) with four layers. The top and bottom layers were not
metalized. The two inner layers, comprising two-ounce
