LTC3600

3600fb

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. Absolute Maximum Ratings are those values

beyond which the life of a device may be impaired.

Note 2: The LT3600 is tested under pulsed load conditions such that

TJ ≈ TA. The LT3600E is guaranteed to meet performance specifications

from 0°C to 85°C junction temperature. Specifications over the

–40°C to 125°C operating junction temperature range are assured by

design, characterization and correlation with statistical process controls.

The LT3600I is guaranteed over the full –40°C to 125°C operating

junction temperature range. 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. The junction temperature

(TJ, in °C) is calculated from the ambient temperature (TA, in °C) and

power dissipation (PD, in watts) according to the formula:

TJ = TA + (PD • θJA), where θJA (in °C/W) is the package thermal

impedance.

Note 3: Dynamic supply current is higher due to the internal gate charge

being delivered at the switching frequency.

Note 4: The LTC3600 is tested in a feedback loop that adjusts VOUT to

achieve a specified error amplifier output voltage (ITH).

Note 5: This IC includes overtemperature protection that is intended

protect the device during momentary overload conditions. Junction

temperature will exceed 125°C when overtemperature protection is active.

Continuous operation above the specified maximum operating junction

temperature may impair device reliability.

Note 6: Duration of voltage transient is less than 20ns for each switching

cycle.
