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 is tested under pulsed load conditions such that T
The LTC3803E is guaranteed to meet specifi cations 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 is guaranteed to
meet performance specifi cations over the –40°C to 125°C operating junction
temperature range, the LTC3803H is guaranteed to meet performance
specifi cations over the –40°C to 150°C operating junction temperature range
and the LTC3803MP is tested and guaranteed over the full –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 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: T
dissipation P
Note 4: Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
Note 5: The LTC3803 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
