Notes:

(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 under “recommended operating con-

ditions” is not implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.

(2) All voltage values are with respect to network ground terminal.

Note 1: For best performance, an inductor with a saturation current rating higher than the maximum input current requirement plus the

inductor current ripple. See Inductor Selection section to determine input current and ripple current.

Note 2: For best performance, a low ESR ceramic capacitor should be used.

Note 3: For best performance, a low ESR ceramic capacitor should be used. If CBYPASS is not a low ESR ceramic capacitor, a 0.1uF ceramic

capacitor should be added in parallel to CBYPASS.

Note 4: Values shown for 5V output.
