(1)
All limits at room temperature (TJ = 25°C) unless otherwise specified. All room temperature limits are 100% production tested. All limits
at temperature extremes are via 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 LM2590HV-AQ-Q1 is used as shown in the Figure 24 test circuit, system performance will be as shown in system parameters
section of Electrical Characteristics.
