output current is brought back into its specified range.
Input Reflected-Ripple Current Test Setup
Overvoltage Protection
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.

Input Source Impedance
Load
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.
-Out
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.

By using a good quality low Equivalent Series Resistance
(ESR < 1.0[ at 100 kHz) capacitor of a 12uF for the 12V,
4.7uF for the 24V input devices and a 2.2uF for the 48V
devices, capacitor mounted close to the power module helps
ensure stability of the unit.

-Vin
The output overvoltage clamp consists of control circuitry,
which is independent of the primary regulation loop, that
monitors the voltage on the output terminals.
The control loop of the clamp has a higher voltage set
point than the primary loop.
This provides a redundant voltage control that reduces the
risk of output overvoltage.

Load
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.
Design & Feature Considerations
+
Maximum Capacitive Load
The MIW5000 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

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 95°C.
The derating curves were determined from measurements
obtained in an experimental apparatus.
