NOTES
1. The DCMJU10 series requires a minimum output loading to maintain specified regulations. Operation under no-load conditions will not
damage these devices; however they may not meet all listed specifications.
2. Transient recovery time is measured to within 1% error band for a step change in output load from 75% to 100%.
3. All DC/DC converters should be externally fused at the front end for protection.
4. To order the converter with a heatsink, please add the suffix “HS” to the model number. (Ex: DCMJU24S12-10HS)
5. Other input and output voltages may be available; please call factory for ordering details.
*Due to advances in technology, specifications subject to change without notice.

DERATING CURVES
Derating Curve without Heatsink
Derating Curve with Heatsink
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 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 1V. A logic high is 2.5V to 50V. The maximum
sink current at on/off terminal during a logic low is -500µA. The maximum allowable leakage current of the switch at on/off
terminal (2.5V to 50V) is 500µA.
Over Current Protection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can
endure overload 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.
A 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 100KHz) capacitor of 6.8µF for the 24V and 48V devices.
Maximum Capacitive Load
The DCMJU10 series has a limitation of maximum connected capacitance on the output. The power module may be
operated in current limiting mode during start-up, affecting the ramp-up and the start-up time. The maximum capacitance can
be found in the model selection table.

DESIGN & FEATURE CONSIDERATIONS
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 4.7µF 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 a test setup.
TEST CONFIGURATIONS
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with an 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.
Peak-to-Peak Output Noise Measurement Test
Use a 0.47µF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 020MHz. Position the load between 50mm and 75mm from the DC/DC converter.
