PRODUCT OVERVIEW
The MINMAX MCWI03 series is a range of isolated 3W 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 (0.3 square in.) on the PCB.
An excellent efficiency allows an operating temperature range of -40°C to +85°C (with derating). Further features include remote On/Off control and overload protection. The very compact dimensions of these DC/DC converters make them an ideal solution for many space critical applications inbattery-powered equipment and instrumentation.

Notes
12345678Specifications typical at Ta=+25℃, resistive load, nominal input voltage, rated output current unless otherwise noted.
Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.
Ripple & Noise measurement bandwidth is 0-20 MHz.
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.
All DC/DC converters should be externally fused at the front end for protection.
Other input and output voltage may be available, please contact factory.

Design & Feature Considerations

inar

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. The switch can be an open collector or equivalent.
A logic high is 2.7V to 15V. A logic low is under 0.6 VDC or open circuit, drops down to 0VDC by 2mV/℃. The maximum sink current at on/off terminal during alogic low is 1 mA. The maximum allowable leakage current of the switch at on/off terminal= (under 0.6VDC or open circuit) is 1mA.
Maximum Capacitive LoadThe MCWI03 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.

imOvercurrent Protection+DC PowerSource-Pr

elTo 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 backinto 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 < 1.0Ωat 100 KHz) capacitor of a 3.3uF for the 12V input devices and a 1.5uF for the 24V and 48V devices.

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 isrecommended to use 3.3uF 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 themaximum temperature rating of the components inside the power module, the case temperature must be kept below 90℃. The derating curves are determinedfrom measurements obtained in an experimental apparatus.
