LTC3803-5
ELECTRICAL CHARACTERISTICS
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 LTC3803-5 is tested under pulsed load conditions such
that T
from 0°C to 85°C junction temperature. Specifi cations over the –40°C
to 125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3803I-5 is guaranteed over the –40°C to 125°C operating junction
temperature range, the LTC3803H-5 is guaranteed over the –40°C to
150°C operating junction temperature range and the LTC3803MP-5 is
tested and guaranteed over the full –55°C to 150°C operating junction
temperature range. Note that the maximum ambient temperature
consistent with these specifi cations is determined by specifi c operating
conditions in conjunction with board layout, the rated package thermal
impedance and other environmental factors.

Note 3: High junction temperatures degrade operating lifetimes; operating
lifetime is derated for junction temperatures greater than 125°C.
Note 4: Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
Note 5: The LTC3803-5 is tested in a feedback loop that servos V
output of the error amplifi er while maintaining I
the current limit range.
Note 6: Peak current sense voltage is reduced dependent on duty cycle
and an optional external resistor in series with the SENSE pin (R
details, refer to the programmable slope compensation feature in the
Applications Information section.
Note 7: Guaranteed by design.
