Note 1: Absolute Maximum Rating indicate limits beyond which damage to the device may occur. Operating Rating indicate conditions for
which the device is intended to be functional, but do not guaranteed specific performance limits. For guaranteed specifications and
test conditions, see the Electrical Characteristics.
Note 2: All limits guaranteed at room temperature (standard type face) and at temperature extremes (bold type face).
Note 3: External component such as the catch diode, inductor, input and output capacitors can affect switching regulator system
performance. When the G5ELM2576 is used as shutdown in the Figure 2 test circuit, system performance will be as shown in
system parameters section of Electrical Characteristics.
Note 4: Output pin sourcing current. No diode, inductor or capacitor connected to output.
Note 5: Feedback pin removed from output and connected to 0V.
Note 6: Feedback pin removed from output and connected to +12V for the Adjustable, 3.3V and 5V versions, and +25V for the 12V and
15V versions, to force the output transistor OFF.
Note 7: V
IN
=40V.
Note 8: The oscillator frequency reduces to approximately 11 kHz in the event of an output short or an overload which causes the
regulated output voltage to drop approximately 40% from the nominal output voltage. This self protection feature lowers the average
power dissipation of the IC by lowering the minimum duty cycle from 5% down to approximately 2%.
