LTM8033
APPLICATIONS INFORMATION
resulting in impaired performance or reliability. Please
refer to the PCB Layout section for printed circuit board
design suggestions.
The LTM8033 is equipped with a thermal shutdown that
will inhibit power switching at high junction temperatures.
The activation threshold of this function, however, is above
125°C to avoid interfering with normal operation. Thus,
it follows that prolonged or repetitive operation under a
condition in which the thermal shutdown activates neces-
sarily means that the internal components are subjected
to temperatures above the 125°C rating for prolonged
or repetitive intervals, which may damage or impair the
reliability of the device.
Finally, be aware that at high ambient temperatures the
internal Schottky diode will have significant leakage cur-
rent (see the Typical Performance Characteristics section)
increasing the quiescent current of the LTM8033.
