This is very simple electronic circuit project of dual step-down power-supply (smps) controller circuit using the MAX17031. Dual step-down power-supply (SMPS) controller can be designed a very simple high efficiency power supply circuit with synchronous rectification, intended for main 5V/3.3V power generation in battery-powered systems. Dual Step-Down Power-Supply (SMPS) Controller Circuit Diagram: Low-side MOSFET sensing provides a simple low-cost, highly efficient current sense for valley current-limit protection. Combined with the output overvoltage and undervoltage protection features, this current limit ensures robust output supplies. The device includes independent shutdown controls with well-defined logic thresholds to simplify power-up and power-down sequencing. To prevent current surges at startup, the internal voltage target is slowly ramped up from zero to the final target over a 1ms period. The Max17031 can be used in applications like : Notebook Computers , Ultra-Mobile P...

Allen Bradley SLC Controller Error Codes  Major Faults/Errors can be classified as: Non-user - a fault caused by various conditions that cease ladder program execution.   The user-fault routine is not run when this fault occurs. Non-recoverable - a fault caused by the user that cannot be recovered from.   The user-fault routine is run when this fault occurs.   However, the fault cannot be cleared. Recoverable - a fault caused by the user that can be recovered from in the user-fault routine by resetting major error halted bit (S:1/13).   The user-fault routine is run when this fault occurs. If you are looking for the explanation of an error that does not appear in this table, it is probably an I/O error.   Refer to either method listed next to clear faults) Clearing Major Errors (via status display) Clearing Faults (via menu selection)  Code (Hex) Description 0001 NVRAM (non-volatile memory) error occurred.   This non-user error occurs...
