Electrical Characteristics
AVIN = PVIN = 5V unless otherwise indicated under the
Conditions
column.
Typicals and limits appearing in plain type apply for T
= T
= +25C. Limits appearing in
boldface
type apply over full
Operating Junction Temperature Range (40C to +125C). Datasheet min/max specification limits are guaranteed by design,
test, or statistical analysis. (Continued)

Note 1:
Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating Range indicates conditions for which the device is
intended to be functional, but does not guarantee specfic performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2:
Human body model: 1.5k
in series with 100pF. SW and PVIN pins are derated to 1.5kV
Note 3:
V
OUT
measured in a non-switching, closed-loop configuration at the SNS pin.
Note 4:
The enable pin is internally pulled up, so the LM2852 is automatically enabled unless an external enable voltage is applied.
