Electrical Characteristics (continued)

Notes:

() 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

(3) Guaranteed by design — not tested in production.
