52 KHz 3A Step-Down

Switching Voltage Regulator (SVR)

NIKO-SEM

GENERAL DESCRIPTION

FEATURES

The N2576 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.

Pin compatible with industry products of

LM2576 Series

Adjustable output versions

Wide output voltage range, 1.23V to 27V

for adjustable output version

DC-to-DC buck converter requiring only 4

external parts

The N2576 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 N2576 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.

52 KHz fixed frequency internal oscillator

TTL shutdown capability, low power stand

-by mode

High efficiency

Uses readily available standard inductors

APPLICATIONS

Simple high-efficiency step-down (buck)

regulator

Positive to negative converter (Inverting

Buck-Boost)

Isolated Fly back Converter using mini-

mum number of external parts

Powering portable instrument, Set-Top

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

SMPS Post-Regulator
