• Manufacturer: LINER [Linear Technology]

ELECTRICAL CHARACTERISTICS
LT3758
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 LT3758E is guaranteed to meet performance specifi cations
from the 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
erature range, otherwise specifi cations are at T

LT3758I is guaranteed over the full –40°C to 125°C operating junction
temperature range.
Note 3: The LT3758 is tested in a feedback loop which servos V
reference voltages (1.6V and –0.8V) with the VC pin forced to 1.3V.
Note 4: FBX overvoltage lockout is measured at V
