Minmax's MSIW1000 3W DC/DC's are in "gull-wing" SMT package and
meet 245]/10sec in solder-reflow for lead free process.
The series consists of 21 models that operate over input voltage ranges of
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 3W and a typical full-load
efficiency of 83%, continuous short circuit, 50mV output ripple, built-in filtering
for both input and output minimize the need for external filtering.
The MSIW1000 units are available in tape and reel package.

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. These power converters require a minimum
output loading to maintain specified regulation.
4. Operation under no-load conditions will not
damage these modules; however, they may not
meet all specifications listed.
Lead Temperature (1.5mm from case for 10 Sec.)
Internal Power Dissipation
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.
