NIKO-SEM
52 KHz 3A Step-Down
Switching Voltage Regulator (SVR)
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.
