LM2576BM  
PIN FUNCTIONS  
+VIN This is the positive input supply for the IC switching regulator. A suitable input  
bypass capacitor must be present at this pin to minimize voltage transients and to supply the  
switching currents needed by the regulator.  
Ground Circuit ground.  
Output Internal switch, the voltage at this pin switches between (+VIN VSAT) and  
approximately -0.5V. To minimize coupling to sensitive circuitry, the PC board copper area  
connected to this pin should be kept to a minimum.  
FeedBack Senses the regulated output voltage to complete the feedback loop.  
—Allows the switching regulator circuit to be shut down using logic level signals. Pulling  
this pin below a threshold voltage of approximately 1.5V turns the regulator on, and  
shutdown feature is not needed, the ON/OFF pin can be wired to the ground pin or it can be  
left open, in either case the regulator will be in the ON condition.
