(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to network ground pin.
(3) DC voltage rating.
(4) AC voltage rating.
(5) Maximum continuos average input current 3.5A, under those condition do not exceed 105°C for more than 25% operating time.

(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.

(1) Refer to the Application Information section for further information
(2) Effective inductance value at operating condition. The nominal value given matches a typical inductor to be chosen to meet the
inductance required.
(3) Due to the dc bias effect of ceramic capacitors, the effective capacitance is lower then the nominal value when a voltage is applied. This
is why the capacitance is specified to allow the selection of the nominal capacitor required with the dc bias effect for this type of
capacitor. The nominal value given matches a typical capacitor to be chosen to meet the minimum capacitance required.
