Minmax's MSIW1000 3W DC/DC's are in"gull-wing" SMT package and meet 245°C/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°C to +71°C 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°C, resistive load, nominal input voltage, rated output current unless otherwise noted.
2. Transient recovery time is measured to within 1% error band for a load step change of 75% to 100%.
3. These power converters require a minimum output load to maintain specified regulation.
4. Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed
5. All DC/DC converters should be externally fused at the front end for protection.
6. Other input and output voltage may be available, please contact factory.
7. All specifications subject to change without notice.
