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 LTC3766E is guaranteed to meet specifications from 0°C
to 85°C with specifications over the –40°C to 125°C operating junction
temperature range assured by design, characterization and correlation with
statistical process controls. The LTC3766I is guaranteed over the –40°C to
125°C operating junction temperature range, the LTC3766H is guaranteed
over the –40°C to 150°C operating junction temperature range, and the
LTC3766MP is tested and guaranteed over the –55°C to 150°C operating
junction temperature range. High junction temperatures degrade operating
lifetimes; operating lifetime is derated for junction temperatures greater
than 125°C. 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: TJ is calculated from the ambient temperature, TA, and power
dissipation, PD, according to the following formula:
TJ = TA + (PD θJA°C/W)
where
θJA is 95°C/W for the SSOP and 43°C/W for the QFN package.
Note 4: The LTC3766 is tested in a feedback loop that servos VFB to a
voltage near the internal 0.6V reference voltage to obtain the specified ITH
voltage (VITH = 1.2V).
Note 5: Operating supply current is measured in test mode. Dynamic
supply current is higher due to the internal gate charge being delivered at
the switching frequency. See Typical Performance Characteristics.
Note 6: The VIN Regulator employs an external pass device to produce the
regulated VCC output voltage. The LTC3766 is tested using a 2N3904 NPN
transistor as an external pass device.
Note 7: Guaranteed by design.
