Minmax's 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 36-75VDC which provide
precisely regulated output voltages of 3.3V, 5V, 12V, 15V, {5V,
{12V and {15VDC.

The MDW1000 series is an excellent selection 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 2W and a typical

full-load efficiency of 81%, continuous short circuit, 30mV 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

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.
