Absolute Maximum Ratings
Stresses exceeding the Absolute Maximum Ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Note:
1. IO(AV) is rated using Fairchild’s DrMOS evaluation board, at TA = 25°C, with natural convection cooling. This rating
is limited by the peak DrMOS temperature, TJ = 150°C, and varies depending on operating conditions and PCB
layout. This rating can be changed with different application settings.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.

Note:
2. Operating at high VIN can create excessive AC overshoots on the VSWH-to-GND and BOOT-to-GND nodes
during MOSFET switching transients. For reliable DrMOS operation, VSWH-to-GND and BOOT-to-GND must
remain at or below the Absolute Maximum Ratings shown in the table above. Refer to the “Application
Information” and “PCB Layout Guidelines” sections of this datasheet for additional information.
