Test Configurations
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 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
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.
Overvoltage Protection
To Oscilloscope
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.
The OVP level can be found in the output data.
Peak-to-Peak Output Noise Measurement Test
Input Source Impedance
Use a Cout 1.0uF ceramic capacitor.
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.
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.

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 < 1.0[ at 100
KHz) capacitor of a 22uF for the 12V input devices and a
6.8uF for the 24V and 48V devices.

Design & Feature Considerations
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 -0V to 1.0V.
A logic high is 2.5V to 100V.
The maximum sink current at on/off terminal during a logic
low is -100 uA.
The maximum allowable leakage current of the switch at
on/off terminal (2.5 to 100V) is 5uA.

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 4.7uF
capacitors at the output.

Maximum Capacitive Load
The MKW3000 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.
For optimum performance we recommend 270uF
maximum capacitive load for dual outputs, 680uF capacitive
load for 12V & 15V outputs and 6800uF capacitive load for
3.3V & 5V outputs.
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°C.
The derating curves are determined from measurements
obtained in an experimental apparatus.
