This is the maximum voltage that can be applied to the output pins. Voltage cannot be applied externally to the output pin of a 3-terminal regulator, but a voltage from 0 V to the rated value can be applied to the output pin (s) of a control IC.
This is the current that flows into the on-chip output transistors.
Miss-operation prevention circuit for low level supply voltage
This circuit stops operation of the IC until the operation start voltage is reached after the power supply voltage rises. It also stops operation when the power supply voltage drops to a certain level.
This is the current that flows in the IC when operation has been stopped by the miss-operation prevention circuit for low level supply voltage. The smaller the standby current, the better.
Circuit (operating) current
This is the current that flows in the IC while the IC is operating. The smaller the circuit current, the better.
The threshold voltage values are the upper and lower limits of the triangular waveform generated by the IC internally. The output duty at the threshold voltage is either 0% or 100% (or maximum value in the case of the uPC494) .
This means the synchronous operation of multiple switching regulators via the on-chip oscillator of another switching regulator IC.
