N2576G-3.3

www.DataSheet4U.com NIKO-SEM 52 KHz 3A Step-Down Switching Voltage Regulator (SVR) FEATURES N2576G-3.3 TO-220, TO263 Lead-Free 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. l Pin compatible with industry products of LM2576G Series l Fixed 3.3V output version l Wide output voltage range, 1.23V to 27V for adjustable output version l DC-to-DC buck converter requiring only 4 external parts l 52 KHz fixed frequency internal oscillator l TTL shutdown capability, low power stand -by mode l High efficiency l Uses readily available standard inductors APPLICATIONS l Simple high-efficiency step-down (buck) regulator l Positive to negative converter (Inverting Buck-Boost) l Isolated Fly back Converter using minimum number of e...
