LTC4070
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
junction temperature range. V NTC = V CC , T A = 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)

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 LTC4070 is tested under pulsed load conditions such that
T J ≈ T A . The LTC4070E is guaranteed to meet performance specifications
for junction temperatures from 0°C to 85°C. Specifications over the
–40°C to 125°C operating junction temperature range are assured by
design, characterization and correlation with statistical process controls.
The LTC4070I 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 operating
conditions in conjunction with board layout, the rated package thermal
resistance and other environmental factors.
Note 3: The I DRV(SNK) current is tested by pulling the DRV pin up to V CC
through a 475k resistor, R DRV . Pulling the DRV pin up to V CC with low
impedance disables the regulator.
