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 LTC3563 is guaranteed to meet performance speci?cations
from 0°C to 85°C. Speci?cations 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 40°C/W.
Note 4: The converter is tested in a proprietary test mode that connects
the output of the error ampli?er 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: T J is calculated from the ambient temperature T A and power
dissipation P D according to the following formula:
T J = T A + (P D ) ? ( θ JA ).
