UMW LM2576/LM2576HV  
Description  
The  
series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching  
LM2576  
regulator, capable of driving 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V,  
5V, 12V, 15V, and an adjustable output versions. Requiring a minimum number of external components, these regulators are simple to  
use and include internal frequency compensation and  
a
fixed-frequency oscillator. The LM2576  
series offers  
a
high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some  
cases no heat sink is required. A standard series of inductors optimized for use with the LM2576 are available from several different  
manufacturers. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed ± 4%  
tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External  
shutdown is included, featuring 50µA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as  
thermal shutdown for full protection under fault conditions.  
Note: TheLM2576HV is not produced yet.
