Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Absolute maximum voltage at VIN and EN/UVLO pins is 60V for nonrepetitive 1 second transients, and 36V for continuous operation. Note 3: The LT3689E 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 LT3689I is guaranteed over the full –40°C to 125°C operating junction temperature range. The LT3689H is 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. Note 4: Current limit is guaranteed by design and/or correlation to static test. Slope compensation reduces current limit at higher duty cycles. Note 5: This IC includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature will exceed 150°C when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability. Note 6: The output of RST and WDO has a weak pull-up to VOUT of typically 1μA. However, external pull-up resistors may be used when faster rise times are required or for VOH higher than VOUT. Note 7: Polarity specification for all currents into pins is positive. All voltages are referenced to GND unless otherwise specified. Note 8: For the LT3689-5, VOUT is set to 5.5V to ensure the switching. ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating junction temperature range, otherwise specifications are at TA = 25°C. VIN = 12V, VOUT = 5V, unless otherwise noted.
