All limits specified 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 specified via correlation using standard Statistical Quality Control
(SQC) methods.
External components such as the catch diode, inductor, input and output capacitors can affect switching regulator system performance.
When the LM2576/LM2576HV is used as shown in
and
system performance will be as shown in
