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. No pin should exceed 6V.
Note 2: The LTC3542-1 is guaranteed to meet performance specications
from 0°C to 85°C. Specications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 3: Failure to solder the Exposed Pad of the package to the PC board
will result in a thermal resistance much higher than 89°C/W.
Note 4: The converter is tested in a proprietary test mode that connects

the output of the error amplier to the SW pin, which is connected to an
external servo loop.
Note 5: Dynamic supply current is higher due to the internal gate charge
being delivered at the switching frequency.
Note 6: The DFN switch on resistance is guaranteed by correlation to wafer
level measurements.
Note 7: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula:
TJ = TA + (PD) (θJA).
ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. VIN = 3.6V unless otherwise noted.
