Short Circuit Protection
EMI Complies With EN55022 Class A
MTBF > 1,000,000 Hours
Minmax's MIW4000-Series power modules are low-profile
dc-dc converters that operate over input voltage ranges of 9-36VDC
and 18-75VDC and provide precisely regulated output voltages of
3.3V, 5V, 12V, 15V, {5V, {12V and {15V.
The -25] to +71] operating temperature range makes it ideal
for data communication equipments, mobile battery driven
equipments, distributed power systems, telecommunication
equipments, mixed analog/digital subsystems, process/machine
control equipments, computer peripheral systems and industrial robot
systems.
The modules have a maximum power rating of 6W and a typical
full-load efficiency of 86%, continuous short circuit, EN55022 level A
conducted noise compliance minimize design-in time, cost and
eliminate the need for external components.

Note :
1. Specifications typical at Ta=+25], resistive load,
nominal input voltage, 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. Ripple & Noise measurement bandwidth is 0-20
MHz.
4. These power converters require a minimum output
loading to maintain specified regulation.
Lead Temperature (1.5mm from case for 10 Sec.)
Exceeding these values can damage the module. These are not continuous
operating ratings.

5. Operation under no-load conditions will not
damage these devices; however they may not
meet all listed specifications.
6. All DC/DC converters should be externally fused at
the front end for protection.
7. Other input and output voltage may be available,
please contact factory.
