Parallel Operation Start-up (St) If the MQP120 modules are to be used in parallel a droop share methodology must be used to ensure that each converter shares the load equally. The `St' pins should be connected together to ensure reliable start-up. RDroop + + Input - MQP120 St - Load RDroop + St + MQP120 - Overtemperature Warning (Ot) Open collector transistor gives +5 C warning of thermal shutdown. Transistor is referenced to -Vout.
