Note 1. Stresses beyond those liste

d 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.

θJA is measured in the natural convection at TA = 25°C on a Four-layer Richtek Evaluation Board. θJC is measured at

the top of the package.

Note 3. Devices are ESD sensitive. Handling precautions are recommended.

Note 4. The device is not guaranteed to function outside its operating conditions.

Note 5. Guaranteed by design.
