Minmax's MSIW2000 3W DC/DC's are in "gull-wing" SMT package. The series consists of 14 models 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 3W and a typical full-load efficiency of 83%, continuous short circuit, built-in filtering for
both input and output minimize the need for external filtering.
The MSIW2000 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. 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.
7. Other input and output voltage may be available, please contact factory.
8. Specifications subject to change without notice.
9. It is not recommended to use water-washing process on SMT units.
