Typical numbers are at 25°C and represent the most likely norm.
All limits ensured at room temperature (standard type face) and at
temperature extremes (bold type face).
All room temperature limits
are 100% production tested. All limits at
temperature extremes
are ensured via correlation using standard Statistical Quality Control
(SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
External components such as the catch diode, inductor, input and output capacitors, and voltage programming resistors can affect
switching regulator performance. When the LM2674 is used as shown in
andFigure
test circuits, system performance will
be as specified by the system parameters section of the Electrical Characteristics.
