NOTES

1. Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100%.

2. Ripple and noise measured at 20MHz bandwidth.

3. The CMDMW series requires a minimum 10% load on the output to maintain specified regulation. Operation under no-load condition

will not damage these devices, however they may not meet all listed specifications.

4. Other input and output voltages may be available, please contact factory.

5. On/Off control is optional, please contact factory. Control voltage referenced to negative input (-Vin).

6. Heat-sink is optional, consult factory.

7. Chassis Mount Options: No suffix for open frame, “U” suffix for U Channel, and “E” suffix for Enclosed type.
