DESCRIPTION
0.86 x 0.37 x 0.44 inches
21.8 x 9.3 x 11.2 mm
The DCMCU2 series of DC/DC power converters consists of fully regulated single and dual
output models with 4:1 ultra wide input voltage ranges of 4.5-18 VDC, 9-36 VDC, and 18-75
VDC. These converters provide 2 Watts of output power in a very small SIP-8 package
occupying only 0.32 square inches on the PCB. An excellent efficiency allows an operating
temperature range up to +75°C at full load without derating. Further features include 1500VDC
I/O isolation, remote on/off control, and short circuit protection. These converters are RoHS
compliant and have CSA/UL/IEC/EN 60950-1 safety approvals. These converters’ very
compact dimensions make them an ideal solution for many space critical applications in
battery powered instrumentations.

TEST CONFIGURATIONS
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 0-20MHz.
Position the load between 50mm and 75mm from the DC/DC converter.
DESIGN & FEATURE CONSIDERATIONS
Remote On/Off
Negative logic remote on/off turns the module OFF during a logic high voltage on the remote on/off pin and ON 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. A logic high
is 2~4mA current applied via 1KΩ resistor. A logic low is open circuit or high impedance.
Maximum Capacitive Load
The DCMCU2 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.
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 4.7µF for 12VDC nominal input models and 2.2µF for 24VDC and 48VDC nominal
input models.
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 3.3µF capacitors at the output.

DESIGN & FEATURE CONSIDERATIONS
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 a test setup.
