Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but does not guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics.
Note 2:
The human body model is a 100 pF capacitor discharged through a 1.5 k
resistor into each pin. Test Method is per JESD-22-A114.
Note 3:
VCC provides self bias for the internal gate drive and control circuits. Device thermal limitations limit external loading.
Note 4:
The input voltage range is dependent on minimum on-time, off-time, and therefore frequency, and is also affected by optimized MOSFET selection.
