MTBF > 1,000,000 Hours
MIW1500-Series power modules are low-profile
dc-dc converters that operate over input voltage ranges of
4.5-9VDC, 9-18VDC, 18-36VDC and provide precisely regulated
output voltages of 5V, 12V, {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 3W and a typical
full-load efficiency of 82%, 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 at no-load will not damage these
units. However, they may not meet all
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.
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.
