Description
Remote Sense with high regulation
Remote ON/OFF
The 75 Watt single ASD-Q series of DC/DC Converters provide
precisely regulated dc outputs. All outputs are fully isolated
from the inputs, allowing the output to be used with positive or
negative polarity and various grounding options. The ASD-Q
Series utilizes an insulated metal substrate design in an industry
standard 1/4 brick case size to meet the most rigorous require-
ments of COTS and thermally challenging industrial applications.
Super energy saving, 6 mA input idle current
Output trim with very low temperature
Water Washable, wide humidity applications
Good shock and vibration damping
Standard features include remote sensing, output trim, and
remote
Threaded-through holes are provided to allow
easy mounting or add a heat sink for extended temperature
use.

NOTES:
(9) When an external
switch is used, such as open collector
switch, logic high requires the switch to be high-impedance.
(1) Refer to the Astrodyne Application Notes for
terms, measurement circuits, and other information.
(2) Refer to the Astrodyne Application Notes for information on fusing.
For inrush current, refer to the above.
Switch leakage currents greater than 20 µA may be
trigger the to the logic-low state.
(10) Most switches would be suitable for logic
to
control, in case
there is a problem, you can make following estimation and then
leave some margin.

to 20 MHz bandwidth (current sensor is located between the
converter input pin and the 12 µH inductor).
Current Allowed for Logic High” are used to estimate the high
impedance requirement of open collector.
(4) Optimum performance is obtained when this power supply is
operated within the minimum to maximum load
No damage to module will occur when the output is operated at
less than minimum load, but the output voltage may contain a
low frequency component that may exceed output noise
.
When switch is used for logic low, “Open Circuit Voltage at On/
Pin”, “Output Resistance” and “LOW Logic Level” are used
to estimate the low impedance requirement of switch.
(11) Thermalimpedanceistestedwiththeconvertermountedvertically
and facing another printed circuit board 1/2 inch away. If
converter is mounted horizontally with no obstructions, thermal
impedance is approximately 10 °C/W.
(5) Load regulation is
as the output voltage change when
changing load current from maximum to minimum. The voltage
is measured at the output pin.
If heat sink is needed, apply a very thin layer of thermally
conductive grease on the metal base of converter, then properly
tighten the screws.
(6) Load Transient Recovery Time is
as the time for the
output to settle from a 50 to 75% or 25% step load change to a
1% error band of output voltage (rise time of step = 2µ Sec).

(8) Noise is measured per the Astrodyne Application Notes. Output
noise is measured with a 10 µF tantalum capacitor in parallel
with a 0.1 µF ceramic capacitor connected across the output to

be used when assessing the applicability in your
manufacturing process. Converters are not hermetically sealed.

less. Greater torque may result in damage to unit and void the
warranty.
