Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Ratings for extended periods may affect device reliability and
lifetime.
Note 2:
The LTC7060E 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
LTC7060I is guaranteed over the −40°C to 125°C operation junction
temperature range. The LTC7060J is guaranteed over the −40°C to 150°C
operation junction temperature range. The LTC7060H is guaranteed over
the −40°C to 150°C operation junction temperature range. High junction
temperature degrades operation lifetimes; operating lifetime is derated
for junction temperatures greater than 125°C. 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 environment factors.
Note 3:
T
J
is calculated from the ambient temperature T
A
and power
dissipation PD according to the following formula
T
J
= T
A
+ (P
D
• 51°C/W) for LFCSP package; T
J
= T
A
+ (P
D
• 40°C/W) for
MSOP package.
Note 4:
The total current includes both the current from BGV
CC
/BST to
BGRTN/SW and the current to SGND. Dynamic supply current is higher
due to the gate charge being delivered at the switching frequency.
Note 5:
Rise and fall times are measured using 10% and 90% levels.
