Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LT4430 is tested under pulsed load conditions such that T
The LT4430E is guaranteed to meet specifi cations from 0°C to 125°C
junction temperature. Specifi cations over the –40°C to 125°C operating
junction temperature range are assured by design, characterization and
correlation with statistical process controls. The LT4430I is guaranteed
over the –40°C to 125°C operating junction temperature range, the
LT4430H is guaranteed over the –40°C to 150°C operating junction
temperature range and the LT4430MP is tested and guaranteed over the
junction temperature range, otherwise specifi cations are at T

.
denotes the specifi cations which apply over the full operating
–55°C to 150°C operating junction temperature range. High junction
temperatures degrade operating lifetimes; operating lifetime is derated
for junction temperatures greater than 125°C. Note that the maximum
ambient temperature consistent with these specifi cations is determined by
specifi c operating conditions in conjunction with board layout, the rated
package thermal impedance and other environmental factors.
Note 3: All currents into device pins are positive. All currents out of device
pins are negative. All voltages are referenced to GND unless otherwise
specifi ed.
Note 4: This parameter is guaranteed by correlation and is not tested.
