Note 11:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the
device is guaranteed. For guaranteed performance limits and associated test conditions, see the Electrical Characteristics table.
Note 12:
Maximum allowable power dissipation is calculated by using P
DMAX
= (T
JMAX
- T
A
)/
θ
JA
, where T
JMAX
is the maximum junction temperature, T
A
is the
ambient temperature and
θ
JA
is the junction-to-ambient thermal resistance of the specified package. The 1.56W rating results from using 150C, 25C, and 80C/W
for T
JMAX
, T
A
, and
θ
JA
respectively. A
θ
JA
of 90C/W represents the worst-case condition of no heat sinking of the 48-pin TSSOP. Heat sinking allows the safe
dissipation of more power. The Absolute Maximum power dissipation should be derated by 12.5mW per C above 25C ambient. The LM2633 actively limits its
junction temperature to about 150C.
Note 13:
For detailed information on soldering plastic small-outline packages, refer to the Packaging Databook available from National Semiconductor Corporation.
Note 14:
Except for ILIM1 and ILIM2 pins, which are 1.5kV. For testing purposes, ESD was applied using the human-body model, a 100pF capacitor discharged
through a 1.5k
resistor.
Note 15:
A typical is the center of characterization data taken with T
A
= T
J
= 25C. Typical data are not guaranteed.
Note 16:
All limits are guaranteed. All electrical characteristics having room-temperature limits are tested during production with T
A
= T
J
= 25C. All hot and cold
limits are guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
Note 17:
This test simulates heavy load condition by changing COMP pin voltage.
Note 18:
This parameter indicates how much current the LM2633 is drawing from the input supply when it is functioning but not driving external MOSFETs or a
bipoloar transistor.
