PRODUCT OVERVIEW
The MINMAX MA03 series is a new range of isolated 3W DC/DC-converter modules in a small SIP-package. There are 12 models available with 5V, 12V or
24VDC input. These products have a typical load regulation of 5.0% to 7.0% depending on model.
The MA03 DC/DC converters are a compromise between a more expensive fully regulated converter and a non-regulated converter. They offer the
designer a new solution for many cost critical applications where the output voltage variation has to be kept in a certain limit under all load conditions.

Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not damage these modules;
however they may not meet all specifications listed.
We recommend to protect the converter by a slow blow fuse in the input supply line.
Other input and output voltage may be available, please contact factory.
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
Specifications are subject to change without notice.

Test Setup
Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.33μF 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.

Technical Notes
Maximum Capacitive Load
The MA03 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 220μF maximum capacitive load for devices. The maximum capacitance can be
found in the data sheet.
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 commended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω
at 100 KHz) capacitor of a 2.2μF for the 5V input devices, a 1.0μF for the 12V input devices and a 0.47μF for the 24V 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 1.0μF 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℃. The derating curves are determined from
measurements obtained in a test setup.
