Minmax's 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 which provide precisely regulated
output voltages of 5V, 12V, 15V, {12V and {15VDC.
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, 45mA output ripple,
built-in filtering for both input and output minimize the need for external
filtering

Notes :
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 modules; however, they may not
meet all specifications listed.

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.
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.
