CAPACITOR RIPPLE CURRENT RMS value of the maximum allowable alternating current at which a capacitor
can be operated continuously at a specified temperature.
STANDBY QUIESCENT CURRENT (ISTBY) Supply current required by the LM2575 when in the standby mode (ON /OFF pin is driven to TTL-high voltage, thus turning the output switch OFF).
INDUCTOR RIPPLE CURRENT ( IIND) The peak-to-peak value of the inductor current waveform, typically a sawtooth waveform when the regulator is operating in the continuous mode (vs. discontinuous mode).
CONTINUOUS/DISCONTINUOUS MODE OPERATION Relates to the inductor current. In the continuous mode,
the inductor current is always flowing and never drops to zero, vs. the discontinuous mode, where the inductor current drops to zero for a period of time in the normal switching cycle.
INDUCTOR SATURATION The condition which exists when an inductor cannot hold any more magnetic flux.
When an inductor saturates, the inductor appears less inductive and the resistive component dominates. Inductor current is then limited only by the DC resistance of the wire and the available source current.
OPERATING VOLT MICROSECOND CONSTANT (E?Top) The product (in VoIt?μs) of the voltage applied to the inductor and the time the voltage is applied. This E?Top constant is a measure of the energy handling capability of an inductor and is dependent upon the type of core, the core area, the number of turns, and the duty cycle.
