LT3758/LT3758A
ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating temp-
erature range, otherwise specifications are at T A = 25°C. V IN = 24V, SHDN /UVLO = 24V, SENSE = 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 LT3758E/LT3758AE are guaranteed to meet performance
specifications from the 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 LT3758I/LT3758AI are guaranteed over the full –40°C to
125°C operating junction temperature range. The LT3758H/LT3758AH are
guaranteed over the full –40°C to 150°C operating junction temperature
range. High junction temperatures degrade operating lifetimes. Operating
lifetime is derated at junction temperatures greater than 125°C. The
LT3758MP/LT3758AMP are 100% tested and guaranteed over the full
–55°C to 150°C operating junction temperature range.
Note 3: The LT3758/LT3758A are tested in a feedback loop which servos
V FBX to the reference voltages (1.6V and –0.8V) with the V C pin forced
to 1.3V.
Note 4: FBX overvoltage lockout is measured at V FBX(OVERVOLTAGE) relative
to regulated V FBX(REG) .
Note 5: Rise and fall times are measured at 10% and 90% levels.
Note 6: SHDN /UVLO = 1.33V when V IN = 5.5V.
Note 7: For V IN below 6V, the SHDN /UVLO pin must not exceed V IN .
Note 8: The LT3758/LT3758A include overtemperature protection that
is intended to protect the device during momentary overload conditions.
Junction temperature will exceed the maximum operating junction
temperature when overtemperature protection is active. Continuous
operation above the specified maximum operating junction temperature
may impair device reliability.
