Note 1:
Absolute maximum ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions for which the device is intended to
be functional, but device parameter specifications may not be guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
The maximum allowable power dissipation is a function of the maximum junction temperature, T
(MAX), the junction-to-ambient thermal resistance,
θ
,
and the ambient temperature, T
A
. See the Electrical Characteristics table for the thermal resistance. The maximum allowable power dissipation at any ambient
temperature is calculated using: P
(MAX) = (T
J(MAX)
T
A
)/
θ
JA
. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown.
Note 3:
The human body model is a 100 pF capacitor discharged through a 1.5k
resistor into each pin. The machine model is a 200pF capacitor discharged
directly into each pin.
Note 4:
All limits guaranteed at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits are 100% tested
or guaranteed through statistical analysis.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:
Typical numbers are at 25C and represent the most likely norm.
Note 6:
Duty cycle affects current limit due to ramp generator.
Note 7:
Current limit at 95% duty cycle. See TYPICAL PERFORMANCE section for Switch Current Limit vs. V
IN
Note 8:
Bias current flows into FB pin.
Note 9:
Refer to National’s packaging website for more detailed thermal information and mounting techniques for the TSSOP package.
