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: Guaranteed by long term current density limitations.
Note 3: The LTC3550E is guaranteed to meet the performance
specifi cations from 0°C to 85°C. Specifi cations over the –40°C to 85°C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 4: Failure to solder the exposed backside of the package to the PC
board will result in a thermal resistance much higher than 40°C/W. See
Thermal Considerations.

Note 5: Supply Current includes IDC and ITERM pin current (approx-
imately 100μA each) but does not include any current delivered to the
battery through the BAT pin (approximately 100mA).
Note 6: Supply Current includes IUSB and ITERM pin current (approx-
imately 100μA each) but does not include any current delivered to the
battery through the BAT pin (approximately 100mA).
Note 7: Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
