UL 94V-0 Package Material
Internal SMD Construction
Minmax's MSDW1000 2W DC/DC's are in "gull-wing" SMT package and
meet 245]/10sec in solder-reflow for lead free process.
The series consists of 28 models 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 -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 2W and a typical full-load
efficiency of 81%, continuous short circuit, 30mV 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
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 the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.
