1
Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
2
Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%
3
Ripple & Noise measurement bandwidth is 0-20MHz.
4
These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these modules;
5
All DC/DC converters should be externally fused at the front end for protection.
however, they may not meet all specifications listed.
6
Other input and output voltage may be available, please contact factory.
7
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).

Test Setup
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with a inductor Lin (4.7μH) and Cin (220μF, ESR < 1.0Ω at 100 KHz) to simulate source impedance. Capacitor Cin, offsets
possible battery impedance. Current ripple is measured at the input terminals of the module, measurement bandwidth is 0-500 KHz.

Technical Notes
Remote On/Off
Positive logic remote on/off turns the module on during a logic high voltage on the remote on/off pin, and off during a logic low. To turn the power module on and off,
the user must supply a switch to control the voltage between the on/off terminal and the -Vin terminal. The switch can be an open collector or equivalent.
A logic low is -0.7V to 0.8V. A logic high is 2.5V to 5.5V. The maximum sink current of the switch at on/off terminal during a logic low is -300 μA.
The maximum sink current of the switch at on/off terminal during a logic high is -200μA or open.
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 at the input to ensure startup.
Capacitor mounted close to the power module helps ensure stability of the unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR <
1.0Ω at 100 KHz) capacitor of a 4.7μF for the 24V input devices and a 2.2μF for the 48V devices.

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 to use 3.3μF capacitors at the output.

Maximum Capacitive Load
The MDWI03 series has limitation of maximum connected capacitance at the output. The power module may be operated 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.
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 105℃. The derating curves are determined
from measurements obtained in a test setup.
