LTC3416
ELECTRICAL CHARACTERISTICS Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 5:
Dynamic supply current is higher due to the internal gate charge of a device may be impaired. The voltage should never exceed 6.0V for any being delivered at the switching frequency. pin.
Note 6:
TJ is calculated from the ambient temperature TA and power
Note 2:
The LTC3416E is guaranteed to meet performance specifications dissipation PD as follows: from 0°C to 85°C. Specifications over the –40°C to 85°C operating LTC3416E: TJ = TA + (PD)(38°C/W) temperature range are assured by design, characterization and correlation
Note 7:
This IC includes overtemperature protection that is intended to with statistical process controls. protect the device during momentary overload conditions. Junction
Note 3:
The LTC3416 is tested in a feedback loop that adjusts VFB to temperature will exceed 125°C when overtemperature protection is active. achieve a specified error amplifier output voltage (ITH). Continuous operation above the specified maximum operating junction
Note 4:
This parameter is guaranteed by design and characterization. temperature may impair device reliability.
