(1)

All limits ensured at room temperature (TJ = 25°C) unless otherwise noted. 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 can affect switching regulator system performance.

When the LM2591HV is used as shown in Test Circuits test circuit, system performance will be as shown in Electrical Characteristics.
