Note 1:
Stresses beyond those listed under Absolute Maximum Ratings specific operating conditions in conjunction with board layout, the rated may cause permanent damage to the device. Exposure to any Absolute package thermal impedance and other environmental factors. The junction Maximum Rating condition for extended periods may affect device temperature reliability and lifetime. (TJ, in °C) is calculated from the ambient temperature (TA, in °C) and
Note 2:
The LTC7150S is tested under pulsed load conditions such power dissipation (PD, in Watts) according to the formula: that TJ ≈ TA. The LTC7150SE is guaranteed to meet specifications from TJ = TA + (PD • θJA), 0°C to 125°C junction temperature. Specifications over the –40°C to where θJA (in °C/W) is the package thermal impedance. 125°C operating junction temperature range are assured by design,
Note 3:
The quiescent current in forced continuous mode does not include characterization and correlation with statistical process controls. The switching loss of the power FETs. LTC7150SI is guaranteed over the –40°C to 125°C operating junction temperature range. The LTC7150SJ-4 is guaranteed over the –40°C to
Note 4:
The LTC7150S is tested in a feedback loop that servos VITH to a 150°C operating junction temperature range. Note that the maximum specified voltage and measures the resultant VFB. ambient temperature consistent with these specifications is determined by
Note 5:
There is additional switch current due to internal resistor to ground. Rev.
