DESCRIPTION/ORDERING INFORMATION  
KTT (TO-263) PACKAGE  
(TOP VIEW)  
The LM2575 greatly simplifies the design of switching  
power supplies by conveniently providing all the  
active functions needed for a step-down (buck)  
switching regulator in an integrated circuit. Accepting  
a wide input voltage range and available in fixed  
output voltages of 3.3 V, 5 V, 12 V, 15 V, or an  
adjustable output version, the LM2575 has an  
integrated switch capable of delivering 1 A of load  
current, with excellent line and load regulation. The  
device also offers internal frequency compensation, a  
fixed-frequency oscillator, cycle-by-cycle current  
limiting, and thermal shutdown. In addition, a manual  
shutdown is available via an external ON/OFF pin.
