PRODUCT OVERVIEW
The MINMAX MCWI02 series is a range of isolated 2W DC/DC converter modules featuring fully regulated output and ultra-wide 4:1 input voltage ranges.
The product comes in a SIP-8 package with a very small footprint occupying only 2.0 cm2 (0.32 square in.) on the PCB.
An excellent efficiency allows an operating temperature range up to 75°C at full load. Further features include remote On/Off control and over load
protection.
The very compact dimensions of these DC/DC converters make them an ideal solution for many space critical applications in battery-powered equipment
and instrumentation.

Notes

Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
2
Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
3
We recommend to protect the converter by a slow blow fuse in the input supply line.
4
Other input and output voltage may be available, please contact factory.

Test Setup
Peak-to-Peak Output Noise Measurement Test
Use a Cout 0.47μF 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
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 power 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 1Kohm resistor. A logic low is open circuit or high impedance.
Maximum Capacitive Load
The MCWI02 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. The maximum capacitance can be found in the data sheet.
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 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 4.7μF for the 12V input devices and a 2.2μF for the 24V and 48V 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 3.3μF 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 105℃. The derating curves are determined from
measurements obtained in a test setup.
