UL 94V-0 Package Material
Internal SMD Construction
Minmax's MIW4000-Series Power modules are low-profile
dc-dc converters that operate over input voltage ranges of 9-36VDC
and 18-75VDC which provide precisely regulated output voltages of
3.3V, 5V, 12V, 15V, {5V, {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 power rating of 6W and a typical
full-load efficiency of 86%, continuous short circuit, 50mA 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.
Lead Temperature (1.5mm from case for 10 Sec.)
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.

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.
