Note 1: The thermal resistance from junction to ambient (θJA) 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.
Note 2: The hysteresis defines the maximum level of acceptable disturbance on VCC during switching.
Note 3: Ground current consists of controller current and regulator current if enabled.
