High Efficiency up to 80% 2:1 Input Range I/O Isolation 1000VDC Industry Standard Pinout SMT Technology Short Circuit Protection MTBF > 1,000,000 Hours External ON/OFF-Control Low Ripple and Noise
MCW1000-Series power modules are low-profile dc-dc converters that operate over input voltage ranges of 4.5-9VDC, 9-18VDC, 18-36VDC and 36-75VDC and provide precisely regulated output voltages of 3.3V, 5V, 12V. The -40] to +65] 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 2W and a typical full-load efficiency of 80%, continuous short circuit, 60mV output ripple, built-in filtering for both input and output minimizes the need for external filtering.

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 all listed specifications. Min. Max. -40 +65 -40 +90 -55 +105 --95 Free-Air Convection Unit ] ] ] % 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.
Exceeding these values can damage the module. These are not continuous operating ratings.
