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