Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a 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:
Supply current in normal operation is dominated by the current
needed to charge and discharge the external FET gates. This will vary with
the LTC1430 operating frequency, operating voltage and the external FETs
used.
Note 5:
The I
LIM
amplifier can sink but cannot source current. Under
normal (not current limited) operation, the I
LIM
output current will be zero.
