LT3755/LT3755-1/LT3755-2 ELECTRICAL CHARACTERISTICSThe l denotes the specifications which apply over the full operatingtemperature range, otherwise specifications are at TA = 25°C. VIN = 24V, SHDN/UVLO = 24V, CTRL = 2V, PWM = 5V, unless otherwise noted.PARAMETERCONDITIONSMINTYPMAXUNITSGate Driver tr GATE Driver Output Rise Time CL = 3300pF 35 ns tf GATE Driver Output Fall Time CL = 3300pF 35 ns GATE Output Low (VOL) 0.05 V GATE Output High (VOH) INTVCC – V 0.05 Note 1: Stresses beyond those listed under Absolute Maximum Ratings Note 3: For VIN below 6V, the SHDN/UVLO pin must not exceed VIN for may cause permanent damage to the device. Exposure to any Absolute proper operation. Maximum Rating condition for extended periods may affect device Note 4: GATE and PWMOUT pins are driven either to GND or INTVCC by reliability and lifetime. internal switches. Do not connect these pins externally to a power supply. Note 2: The LT3755E, LT3755E-1 and LT3755E-2 are guaranteed to meet Note 5: The LT3755 includes overtemperature protection that is intended performance specifications from 0°C to 125°C junction temperature. to protect the device during momentary overload conditions. Junction Specifications over the –40°C to 125°C operating junction temperature temperature will exceed the maximum operating junction temperature range are assured by design, characterization and correlation with when overtemperature protection is active. Continuous operating above statistical process controls. The LT3755I, LT3755I-1 and LT3755I-2 are the specified maximum operating junction temperature may impair device guaranteed to meet performance specifications over the –40°C to 125°C reliability. operating junction temperature range. The LT3755H-2 and LT3577J-2 are guaranteed to meet performance specifications 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. Rev.
