Note 1:
Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the
device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the
Electrical Characteristics tables.
Note 2:
Specification guaranteed by design. Not tested during production.
Note 3:
All limits are guaranteed by design, test and/or statistical analysis. All electrical characteristics having room-temperature limits are tested during production
with T
J = 25°C. All hot and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical
process control.
Note 4:
Capacitors: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) are used in setting electrical characteristics.
Note 5:
Internal thermal shutdown protects device from permanent damage. Thermal shutdown engages at T
J = +140°C and disengages at TJ = +120°C (typ.).
Thermal shutdown is guaranteed by design.
Note 6:
BUCK normal operation is guaranteed if V
IN ≥ VOUT+1.0V.
Note 7:
In applications where high power dissipation and/or poor thermal resistance is present the maximum ambient temperature may have to be derated.
Maximum ambient temperature (T
A-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP = +125°C), the maximum power dissipation of
the device in the application (P
D-MAX), and the junction-to-ambient thermal resistance of the part/package in the application (θJA), as given by the following equation:
T
A-MAX = TJ-MAX-OP – (θJA × PD-MAX).
Note 8:
The amount of Absolute Maximum power dissipation allowed for the device depends on the ambient temperature and can be calculated using the formula:
P = (T
J–TA)/θJA, where TJ is the junction temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance. θJA is highly application
and board-layout dependent. Internal thermal shutdown circuitry protects the device from permanent damage. (See General Electrical Characteristics.)
