MTBF > 1,000,000 Hours
Low Ripple and Noise
EMI Complies With EN55022 Class A
MDW1000-Series power modules are low-profile
dc-dc converters that operate over input voltage ranges of
4.5-9VDC, 9-18VDC, 18-36VDC and 36-72VDC and provide
precisely regulated output voltages of 3.3V, 5V, 12V, 15V, {5V,
{12V and {15V.
The -40 ]+65 ] 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 2 and a typical
full-load efficiency of 80 ] , continuous short circuit, 60mV 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 50%
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
on 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 these values can damage the module. These are not continuous
