ELECTRICAL CHARACTERISTICS

temperature range.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of the device may be impaired.

Note 2: All currents into device pins are positive; all currents out of device

pins are negative. All voltages are referenced to ground unless otherwise

specified.

Note 3: This parameter is guaranteed by correlation and is not tested

directly.

Note 4: LTC1504 quiescent current is dominated by the gate drive current

the output stage will stop switching and the static quiescent current can be

observed. With FB or SENSE hooked up normally, the output stage will be

switching and total dynamic supply current can be measured.

lower than the specified values, due to the internal divider resistors.

Note 7: Contact factory for guaranteed specifications at 2.7V supply.
