MIW1100-Series power modules are low-profile
dc-dc converters that operate over input voltage ranges of
4.5-9VDC, 9-18VDC, 18-36VDC and 36-75VDC and provide
precisely regulated output voltages of 5V, 12V, 15V, {12V and
{15V.
The -40] 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 3W and a typical
full-load efficiency of 81%, continuous short circuit, 60mA output
ripple, built-in filtering for both input and output minimizes the need
for external filtering.

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.
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.
8. Specifications subject to change without notice.
