Note 1.
Stresses beyond those listed under
“Absolute
Maximum Ratings” may cause permanent damage to the device.
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those
indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating
conditions may affect device reliability.
Note 2.
θ
JA
is measured under natural convection (still air) at T
A
= 25°C with the component mounted on a high effective-
thermal-conductivity four-layer test board on a JEDEC 51-7 thermal measurement standard.
θ
JC
is measured at the
exposed pad of the package.
Note 3.
Devices are ESD sensitive. Handling precaution is recommended.
Note 4.
The device is not guaranteed to function outside its operating conditions.
Note 5.
When VIN is beyond the recommended operating voltage (80V) and within the absolute maximum voltage (90V), the
conducting current through SW pin has to be less than 0.5A to avoid instant damage to the devices.
