Minmax's MIW3100-Series Power modules are low-profile dc-dc
converters that operate over input voltage ranges of 9-18VDC and
18-36VDC which provide precisely regulated output voltages of 3.3V,
5V, 12V, {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 powerrating of 6W and a typical
full-load efficiency of 86%, continuous short circuit, 50mA output
ripple, built-in filtering for both input and output minimize design-in
time, cost and eliminate 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.
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.
