Note 1:
Stresses beyond those listed under Absolute Maximum Ratings for junction temperatures greater than 125°C. Note that the maximum may cause permanent damage to the device. Exposure to any Absolute ambient temperature consistent with these specifications is determined by Maximum Ratings for extended periods may affect device reliability and specific operating conditions in conjunction with board layout, the rated lifetime. package thermal impedance and other environment factors.
Note 2:
The LTC7060E is guaranteed to meet performance specifications
Note 3:
TJ is calculated from the ambient temperature TA and power from 0°C to 85°C junction temperature. Specifications over the −40°C dissipation PD according to the following formula to 125°C operating junction temperature range are assured by design, TJ = TA + (PD•51 °C/W) for LFCSP package; TJ = TA + (PD•40 °C/W) for characterization and correlation with statistical process controls. The MSOP package. LTC7060I is guaranteed over the −40°C to 125°C operation junction
Note 4:
The total current includes both the current from BGV temperature range. The LTC7060J is guaranteed over the −40°C to 150°C CC/BST to BGRTN/SW and the current to SGND. Dynamic supply current is higher operation junction temperature range. The LTC7060H is guaranteed over due to the gate charge being delivered at the switching frequency. the −40°C to 150°C operation junction temperature range. High junction temperature degrades operation lifetimes; operating lifetime is derated
Note 5:
Rise and fall times are measured using 10% and 90% levels.
