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.
Note 2:
The LTC7003 is tested under pulsed load conditions such that
T
J
≈ T
A
. The LTC7003E is guaranteed to meet performance specifications
from 0°C to 85°C. Specifications over the –40°C to 125°C operating
junction temperature range are assured by design, characterization and
correlation with statistical process controls. The LTC7003I is guaranteed
over the –40°C to 125°C operating junction temperature range, the
LTC7003H is guaranteed over the –40°C to 150°C operating junction
temperature range and the LTC7003MP is tested and guaranteed over the
–55°C to 150°C operating junction temperature range.
High junction temperatures degrade operating 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 environmental factors.
Note 3:
The junction temperature (T
J
, in °C) is calculated from the ambient
temperature (T
A
, in °C) and power dissipation (P
D
, in Watts) according to
the formula:
T
J
= T
A
+ (P
D
•
θ
JA
), where
θ
JA
is 45°C/W.
Note 4:
This IC includes over temperature protection that is intended to
protect the device during momentary overload conditions. The maximum
rated junction temperature will be exceeded when this protection is active.
Operation above the specified absolute maximum operating junction
temperature may impair device reliability or permanently damage the
device.
Note 5:
Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency. See Applications Information.
Note 6:
For application concerned with pin creepage and clearance
distances at high voltages, the MSE16(12) variation package should be
used. See Applications Information.
Note 7:
Do not apply a voltage or current source to these pins. They must
be connected to capacitive loads only; otherwise permanent damage may
occur.
Note 8:
Total supply current is the sum of the current into the V
