Meets UL1950/EN60950
MIW2100-Series power modules are specially designed to
provide ultra-high levels of isolation 4200VDC in a low profile 24-pin DIP
package. Operating input voltage ranges of 9-40VDC, 18-80VDC and
36-160VDC which provide precisely regulated output voltages of 5V,
12V, {12V and {15VDC.
The -40] to +75] 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, EN55022 Class B
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 at
the front end for protection.
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.
