Series utilizes an insulated metal substrate design in an industry
standard 1/4 brick case size to meet the most rigorous requirements of COTS and thermally challenging industrial applications.
Remote Sense with high regulation
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.
Good shock and vibration damping

NOTES:

ASD75-24S12Q
ASD75-48S12Q
Refer to the Astrodyne Application Notes for
terms, measurement circuits, and other information.
Refer to the Astrodyne Application Notes for information on fusing.
For inrush current, refer to the
above.
33 µF capacitor connected to two “Input” pins. Then place
current sensor in series with 12 µH inductor between 33 µF and
the source. The
ripple current is measured over 5 Hz
to 20 MHz bandwidth (current sensor is located between the
converter input pin and the 12 µH inductor).
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
.
Load regulation is
as the output voltage change when
changing load current from maximum to minimum. The voltage
is measured at the output pin.
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).
as the peak overshoot
Load Transient Overshoot is
during a transient as
in the Note 6 above.
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
CMN. Measurement bandwidth is 0-20 MHz.

switch is used, such as open collector
When an external
switch, logic high requires the switch to be high-impedance.
Switch leakage currents greater than 20 µA may be
to
trigger the
to the logic-low state.
Most switches would be suitable for logic
control, in case
there is a problem, you can make following estimation and then
leave some margin.
When open collector is used for logic high, “Open Circuit Voltage
at
Pin”, “Output Resistance” and “External Leakage
Current Allowed for Logic High” are used to estimate the high
impedance requirement of open collector.
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.
Thermal impedance is tested with the converter mounted vertically
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.
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.
Water Washability - These DC/DC converters are designed to
withstand most solder/wash processes. Careful attention should
c
be used when assessing the applicability in your
manufacturing process. Converters are not hermetically sealed.
Torque fasteners into threaded mounting inserts at 12 in. oz. or
less. Greater torque may result in damage to unit and void the
warranty.
