PRODUCT OVERVIEW
The MINMAX MJWI15 series are cost optimized dc-dc converter modules offering 15W output power in a 1"x1"x 0.4" shielded metal package with industry
standard pinout. All models provide ultra-wide 4:1 input voltage range and tight output voltage regulation.
State-of-the-art circuit topology provides a high efficiency up to 91% allowing an operating temperature range of -40°C to +90°C
For increased temperature performance the modules are available with an optional clip-on heatsink.
Further features include remote On/Off control,trimmable output voltage, overload and overvoltage protection.
Typical applications for these dc-dc converters are battery operated equipment, instrumentation, distributed power architectures in communication and
industrial electronics and other space critical applications.

Specifications typical at Ta=+25℃, resistive load, nominal input voltage and 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 measured with a 1μF MLCC.
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.
To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required.
Suggested capacitor : XXS033, XXS05: CHEMI-CON KY Series 470μF/100V.
Other Models: CHEMI-CON KY Series 220μF/100V.
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
Specifications are subject to change without notice.

►The advantages of adding a
heatsink are:
1. To improve heat dissipation and increase the
stability and reliability of the DC/DC converters at
high operating temperatures.
2. To increase operating temperature of the DC/DC
converter, please refer to Derating Curve.

DC/DC CONVERTER 15W, High Power Density
Test Setup
Input Reflected-Ripple Current Test Setup
Input reflected-ripple current is measured with a 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 1μF ceramic capacitor. Scope measurement should be made by using a BNC socket, measurement bandwidth is 0-20 MHz. Position the load between 50 mm

Technical Notes
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 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
low is 0V to 1.2V. A logic high is 3.5V to 12V. The maximum sink current at the on/off terminal (Pin 6) during a logic low is -500μA. The maximum allowable leakage
current of a switch connected to the on/off terminal (Pin 6) at logic high (3.5V to 12V) is 10mA.
Overload Protection
To provide hiccup mode protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry and can endure overload for an
unlimited duration.
Overvoltage Protection
The output overvoltage clamp consists of control circuitry, which is independent of the primary regulation loop, that monitors the voltage on the output terminals.
The control loop of the clamp has a higher voltage set point than the primary loop. This provides a redundant voltage control that reduces the risk of output
overvoltage. The OVP level can be found in the output data.
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 recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0
Ω at 100 KHz) capacitor of a 10μF 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 4.7μF capacitors at the output.

Maximum Capacitive Load
The MJWI15 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.
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.
