N2576G-3.3

TO-220, TO263

Lead-Free

52 KHz 3A Step-Down

Switching Voltage Regulator (SVR)

NIKO-SEM

GENERAL DESCRIPTION

FEATURES

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.

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

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 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 mini-

mum number of external parts

l Powering portable instrument, Set-Top

Box, LCD Monitor, Scanner, I.A, Easy PC

l SMPS Post-Regulator
