ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
junction temperature range, otherwise specifications are for TA = 25°C (Note 2). Unless otherwise noted, VIN = 5.5V.

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 LTC3388-1/LTC3388-3 are tested under pulsed load conditions
such that TJ ≈ TA. The LTC3388E-1/LTC3388E-3 are guaranteed to meet
specifications from 0°C to 85°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 LTC3388I-1/LTC3388I-3 are guaranteed over the –40°C to 125°C
operating junction temperature range. Note that the maximum ambient
temperature consistent with these specifications is determined by specific
operating conditions in conjunction with board layout, the rated package
thermal impedance and other environmental factors.
Note 3: The junction temperature (TJ, in °C) is calculated from the ambient
temperature (TA, in °C) and power dissipation (PD, in Watts) according
to the formula: TJ = TA + (PD θJA), where θJA (in °C/W) is the package
thermal impedance.
Note 4: Dynamic supply current is higher due to gate charge being
delivered at the switching frequency.
