(1)

All room temperature limits are 100% production tested. All limits at temperature extremes are ensured through correlation using

standard Statistical Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).

(2)

Typical numbers are at 25°C and represent the most likely norm.

(3)

External components such as the catch diode, inductor, input and output capacitors, and voltage programming resistors can affect

switching regulator performance. When the LM2671 is used as shown in Figure 15 and Figure 21 test circuits, system performance is as

specified by the system parameters section of the Electrical Characteristics.
