ELECTRICAL CHARACTERISTICS

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 LTC7000A/LTC7000A-1 is tested under pulsed load conditions

such that TJ ≈ TA. The LTC7000AR/LTC7000AR-1 is specified over –40°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 (TJ, in °C) is calculated from the ambient

temperature (TA, in °C) and power dissipation (PD, in Watts) according to

the formula:

TJ = TA + (PD • θJA), where θJA 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 VIN, SNS+,

SNS– and TS pins.
