–30V to 0.3V Input Voltage SHDN –30V to 30V Output Voltage STATUS –0.3V to 30V Input Current IN 6A Output Current OUT -6A Operating Junction Temperature Range LT4422A –40°C to 125°C Storage Temperature Range –65°C to 150°C .1 All currents into pins are positive; all voltages are referenced to GND unless otherwise noted. 2 The LT4422 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 This voltage is set by the power path MOSFET’s body diode and will safely exceed 0.3V during start-up for a limited time determined by the body diode thermal dissipation.

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.
