Note 1:
Note 2:
Note 3:
The thermal resistance from junction to ambient (
θ
JA
) must be less than 55° C/W. This is typically achieved with 2 square inches of
copper printed circuit board area connected to the GND pins for heat spreading, or equivalent.
The hysteresis defines the maximum level of acceptable disturbance on
V
CC
during switching.
Ground current consists of controller current and regulator current if enabled.
