High Efficiency up to 86% 2:1 Input Range I/O Isolation 1500VDC Industry Standard Pinout SMT Technology Short Circuit Protection EMI Complies With EN55022 Class A MTBF > 1,000,000 Hours
MIW1200-Series power modules are low-profile dc-dc converters that operate over input voltage ranges of 9-18VDC, 18-36VDC and 36-75VDC and provide precisely regulated output voltages of 5V, 12V, 15V, {12V and {15V. The -25] 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 86%, continuous short circuit, 60mA output ripple, EN55022 level A conducted noise compliance minimize design-in time, cost and eliminate the need for external components.

Note :
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 50% 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 devices; however they may not meet.
