1

All currents into pins are positive; all voltages are referenced to GND unless otherwise noted.

2

The LT4423 is tested under pulsed load conditions such that TJ ≈ TA. 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).

3

The LT4423 includes overtemperature protection that is intended to protect the device during momentary

overload conditions. Junction temperature will exceed 150°C when overtemperature protection is active.

Continuous operation above the specified maximum operating junction temperature may impair device

reliability.

4

Determined by design, not tested in production.

5

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.

These are stress ratings only, functional operation of the product at these or any other conditions above those

indicated in the operational section of this specification is not implied. Operation beyond the maximum operating

conditions for extended periods may affect product reliability.
