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 intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Note 3: The Thermal Resistance specifications are based on a JEDEC standard 4-layer pcb. θ
will vary with board size and copper area.

Note 5: All room temperature limits are 100% production tested. All limits at temperature extremes are guaranteed through correlation using standard Statistical
Quality Control (SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
Note 6: IQ specifies the current into the VIN pin and applies to non-switching operation.
Note 7: V
specifies the maximum absolute difference between the offset of any pair of SNS amplifiers.
OS_DELTA
Note 8: The minimum DIM pulse width is an internal signal. Any pulse width may be applied to the DIM pin or generated via analog dimming mode. A pulse width
less than 0.4 µs will be internally extended to 0.4 µs.
