ELECTRICAL CHARACTERISTICS LM2592HV-5.0
Specifications with standard type face are for T
J
= 25°C, and those with boldface type apply over full Operating
Temperature Range.

(1) Typical numbers are at 25°C and represent the most likely norm.
(2) 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).
(3) External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance.
When the LM2592HV is used as shown in the Test Circuit and Layout Guidelines, system performance will be as shown in system
parameters section of Electrical Characteristics.
