Test Configurations
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with a inductor
Lin (4.7uH) and Cin (220uF, ESR < 1.0[ at 100 kHz) to
simulated source impedance.
Capacitor Cin, offsets possible battery impedance.
Current ripple is measured at the input terminals of the
module, measurement bandwidth is 0-500KHz.
Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.47uF ceramic capacitor.
Scope measurement should be made by using a BNC
socket, measurement bandwidth is 0-20 MHz. Position the
load between 50 mm and 75 mm from the DC/DC Converter.
Design & Feature Considerations
Maximum Capacitive Load
The MSDW1000 series has limitation of maximum
connected capacitance on the output.
The power module may operate in current limiting mode
during start-up, affecting the ramp-up and the startup time.
The maximum capacitance can be found in the data sheet.
Overcurrent Protection
To provide protection in a fault (output overload) condition,
the unit is equipped with internal current limiting circuitry and
can endure current limiting for an unlimited duration. At the
point of current-limit inception, the unit shifts from voltage
control to current control. The unit operates normally once the
output current is brought back into its specified range.
Input Source Impedance
The power module should be connected to a low
ac-impedance input source. Highly inductive source
impedances can affect the stability of the power module.
In applications where power is supplied over long lines and
output loading is high, it may be necessary to use a capacitor
on the input to insure startup.
By using a good quality low Equivalent Series Resistance
(ESR < 1.0[ at 100 kHz) capacitor of a 8.2uF for the 5V input
devices, a 3.3uF for the 12V input devices and a 1.5uF for the
24V and 48V devices, capacitor mounted close to the power
module helps ensure stability of the unit.
Output Ripple Reduction
A good quality low ESR capacitor placed as close as
practicable across the load will give the best ripple and noise
performance.
To reduce output ripple, it is recommended that 3.3uF
capacitors are used on output.

Thermal Considerations
Many conditions affect the thermal performance of the
power module, such as orientation, airflow over the module,
and board spacing. To avoid exceeding the maximum
temperature rating of the components inside the power
module, the case temperature must be kept below 90C.
The derating curves were determined from measurements
obtained in an experimental apparatus.

The MSDW1000 converter is encapsulated in a low thermal resistance molding compound that has excellent resistance/electrical
characteristics over a wide temperature range or in high humidity environments.
The encapsulant and unit case are both rated to UL 94V-0 flammability specifications.
