Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which
the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions,
see the Electrical Characteristics.
Note 2: The human body model is a 100pF capacitor discharged through a 1.5k resistor into each pin.
Note 3: Typical numbers are at 25
o
C and represent the most likely norm.
Note 4: All limits guaranteed 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 guaranteed via correlation using standard Statistical Quality Control
(SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
Note 5: External components such as the catch diode, inductor, input and output capacitors, and voltage programming resistors can affect
switching regulator system performance.
Note 6: The switching frequency is reduced when the second stage current limit is activated.
Note 7: No diode, inductor or capacitor connected to output pin.
Note 8: Feedback pin removed from output and connected to 0V to force the output transistor switch ON.
Note 9: Feedback pin removed from output and connected to 12V for the 3.3V, 5V, ADJ. version, and 15V for the 12V version, to force the output
transistor switch OFF.
Note 10: V
IN
=40V.
Note 11: Junction to ambient thermal resistance. (With copper area of approximately 3in
2
)
