GENERAL DESCRIPTION
The N2576G Series switching voltage
regulators (SVR) are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching
regulator, Both series are capable of driving 3 A load respectively with excellent line and load regulation. The N2576G Series SVR include a switching
regulator and compensation network all within the same package. Just add a choke, catch diode and two capacitors to obtain an efficient DC-to-DC converter. The output switch includes cycle-by-cycle current limit -ing, as well as thermal shutdown for full protection under fault conditions. The N2576G Series SVR offer replacement for popular 3 terminal linear
regulators by providing higher efficiency with reduced heat sink size. In many applications a heat sink will not be required.
