All DC/DC converters should be externally fused at the front end for protection.
Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
Ripple and noise measured at 20MHz bandwidth.
The DMW series requires a minimum 10% load on the output to maintain specified regulation. Operation under no-load condition will
not damage these devices, however they may not meet all listed specifications.
Other input and output voltages may be available, please contact factory.
On/Off control is optional, please contact factory. Control voltage referenced to negative input (-Vin).

The Advantages of adding a Heatsink:
1.
To help heat dissipation and increase the stability and
reliability of DC/DC converters at high operating temperature
atmosphere.
2. To upgrade the operating temperature of DC/DC converters,
please refer to the Derating Curve.
The DMW Series 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.
Leads are tin plated for improved solderability.

DESIGN & FEATURE CONSIDERATONS
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 at on/off terminal during a logic low is -1mA. The maximum allowable
leakage current of the switch at on/off terminal (2.5 to 5.5V) is 50uA.
Over Current 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 10uF for the 24V and 48V input devices.
Maximum Capacitive Load
The DMW Series has a 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 220uF maximum capacitive load for dual outputs and 470uF
capacitive load for single outputs. The maximum capacitance can be found in the Output Voltage /
Current Rating Chart.

TEST CONFIGURATIONS
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with an inductor Lin (4.7uH) and Cin (220uF, 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.
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.

Output Ripple Reduction
A good quality low ESR capacitor placed as close as possible 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.
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 100°C. The derating curves are
determined from measurements obtained in an experimental apparatus.
