Key Features
Efficiency up to 82%
1500VDC Isolation
MTBF > 1,000,000 Hours
2:1 Wide Input Range
Low Cost
Complies with EN55022 Class A
Temperature Performance -25] to +71]
UL 94V-0 Package Material
Internal SMD Construction
Industry Standard Pinout
Minmax's MIW1500-Series power modules operate over input
voltage ranges of 4.5-9VDC, 9-18VDC and 18-36VDC which
provide precisely regulated output voltages of 5V, 12V, {12V and
{15VDC.
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, 45mA output
ripple, EN55022 Class A conducted noise compliance 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.

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.
