Minmax's MSKW2000-Series are in “ gull-wing” SMT package. The series consists of 21 models with 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 5W and a typical full-load efficiency of 85%, continuous short circuit,Remote on/off
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 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 processon SMT units.
