ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VIN = 5V, VSHDN = 5V, CAP1-3 = 5V, PWM1-3 = 5V, FADJ = 0.5V,
CTRL1-3 = 1.5V, OVP1-3 = 0V, unless otherwise noted.

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 LT3496E is guaranteed to meet performance specifications
from 0°C to 125°C junction temperature. Specifications over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LT3496I is guaranteed over the full –40°C to 125°C operating junction
temperature range.
Note 3: Current flows into pin. Current limit and switch VCESAT is
guaranteed by design and/or correlation to static test.
Note 4: Absolute maximum voltage at the VIN and SHDN pins is 40V for
nonrepetitive 1 second transients, and 30V for continuous operation.
Note 5: Gate turn-on/turn-off delay is measured from 50% level of PWM
voltage to 90% level of gate on/off voltage.
