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 LTC4071 is tested under pulsed load conditions such that
TJ = TA. The LTC4071E is guaranteed to meet performance specifications
for junction temperatures from 0°C to 85°C. Specifications over the
The l denotes the specifications which apply over the full operating
junction temperature range. Conditions are VNTC = VADJ = VCC, VLBSEL = GND, TJ = 25°C unless otherwise specified. Current into a pin
is positive and current out of a pin is negative. All voltages are referenced to GND unless otherwise noted. (Note 2)
–40°C to 125°C operating junction temperature range are assured by
design, characterization and correlation with statistical process controls.
The LTC4071I is guaranteed over the full –40°C to 125°C operating
junction temperature range. Note that the maximum ambient temperature
consistent with these specifications is determined by specific operation
conditions in conjunction with board layout, the rated package thermal
impedance and other environmental factors.
