LM2576BM

functional, but specific performance is not guaranteed. For guaranteed specifications and

the best conditions, see the Electrical Characteristics.

* 2 All limits guaranteed at room temperature (standard type face) and at temperature

extremes(bold type face). All room temperature limits are 100% production tested. All

limits at temperature extremes are guaranteed via correlation using standard Statistical

Quality Control (SQC) methods.

* 3 External components such as the catch diode, inductor, input and output capacitors, and

voltage programming resistors can affect switching regulator system performance.

* 4 Output pin sourcing current. No diode, inductor or capacitor connected to output pin.

* 5 Feedback pin removed from output and connected to 0V.

* 6 Feedback pin removed from output and connected to +12V for the 3.3V, 5V, and the

ADJ version, to force the output transistor switch OFF.

* 7 V_IN= 40V

* 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. The self-protection feature lowers the average power

dissipation of the minimum duty cycle from 5% down to approximately 2%.
