Description
The 4:1 Input Voltage 100 W single ASD Series of DC/DC
converters provide precisely regulated dc outputs. The
output voltage is fully isolated from the input, allowing the
output to be positive or negative polarity and with various
ground connections. The ASD Series utilizes an
insulated metal substrate design in an industry standard
1/2 brick case size to meet the most rigorous requirements of COTS and thermally challenging industrial
applications.

Notes:
(1) Refer to the Application Notes for the definition of terms,
measurement circuits, and other information.
(2) Refer to the Application Notes for information of fusing.
For inrush current, refer to the specifications above.
(3) 33µF capacitor connected between the two “Input” pins. Then
insert current sensor in series with 1.0µH inductor between
100µF and the source. The reflected ripple current is measured
over a 5 Hz to 20 MHz bandwidth. (current sensor is located
between the converter input pin and the 1.0 µH inductor)
(4) Optimum performance is obtained when this power supply is
operated within the minimum to maximum load specifications.
No damage to the module will occur when the output is operated
at less than minimum load, however, below minimum load the
dynamic response will degrade. Operation below minimum load
is not recommended.
(5) Load regulation is defined as the output voltage change when
changing load current from a maximum to minimum.
(6) Load Transient Recovery Time is defined as the time for the
output to settle from a 50% to 75% step load change to a 1%
error band (rise time of step = 2µs).
(7) Load Transient Overshoot is defined as the peak overshoot
during a transient as defined in the Note 6 above.
(8) Noise is measured per the Application Notes. Output
noise is measured with a 10µF tantalum capacitor in parallel with
a 0.1µF ceramic capacitor connected across the output pins.
Measurement bandwidth is 0-20MHz.
(9) When an external ON/OFF switch is used, such as open collector
switch, logic high requires the switch to be high-impedance.
Switch leakage currents greater than 10µA may be sufficient to
trigger the ON/OFF to the logic-low state.

(10) Most switches would be suitable for the logic ON/OFF control. In
case there is a problem you can make the following estimations and
then leave some margin.
When open collector is used for logic high, “Open Circuit Voltage at
ON/OFF 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/
OFF Pin”, “Output Resistance” and “LOW Logic Level” are used to
estimate the low impedance requirement of the switch.
(11) 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 obstruction, thermal impedance is
approximately 8°C/W.
(12) Water Washability - These DC/DC converters are designed to
withstand most solder/wash processes. Careful attention should be
used when assessing the applicability in your specific manufacturing
process. Converters are not hermetically sealed.
(13) Torque fasteners into threaded mounting inserts at 12 in.lbs. or less.
Greater torque may result in damage to unit and void the warranty.
(14) Input impedance on these units needs to be kept to a minimum. The
9-36Vdc DC units need a maximum input impedance of 0.2 Ohms
and the 18-75Vdc DC units need a maximum input impedance of 0.8
Ohms. In order to support this requirement, the 9-36Vdc DC units
need 25 µF of capacitance (low ESR) for every 1.0 µH of inductance
between the power source and the DC/DC converter. The 18-75Vdc
DC units need 1.7µF of capacitance (low ESR) for every 1.0 µH of
inductance between the power source and the DC/DC converter.
Inductance includes all sources and should take into account input
power lines.
(15) RoHS Compliance:
See Astrodyne Website www.astrodyne.com for the complete
RoHS Compliance statement and Application Notes.
The RoHS marking is as follows.
