Electrical Characteristics (continued)

Notes:

(1)

Thermal limitation is dependent upon the thermal performance of the printed circuit board in support of the package standard of 68° C/W.

(2)

Voltage at the IN pin where a mode transition takes place in the charge pump with V

IN

falling.

(3)

Guaranteed by design - not tested in production.
