DCM300P280x500A40
An array of DCMs used at the full array rated power may generally
have one or more DCMs operating at current limit, due to sharing
errors. Load sharing is functionally managed by the load line.
Thermal balancing is improved by the nominal effective temperature
coefficient of the output voltage setpoint.
DCMs in current limit will operate with higher output current or
power than the rated levels. Therefore the following Thermal Safe
Operating Area plot should be used for array use, or loads that drive
the DCM in to current limit for sustained operation.
