Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
Note 2: TJ is calculated from the ambient temperature TA and power dissipation PD according to the
following formula: TJ = TA + (PD) x (250°C/W).
Note 3: 100% production test at +25°C. Specifications over the temperature range are guaranteed by
design and characterization.
Note 4: Dynamic supply current is higher due to the gate charge being delivered at the switching
frequency.
