Switching Voltage Regulator (SVR)

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.

z Pin compatible with industry products of

LM2576 Series

z Adjustable output versions

z Wide output voltage range, 1.23V to 27V

for adjustable output version

z 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.

z 52 KHz fixed frequency internal oscillator

z TTL shutdown capability, low power stand

-by mode

z High efficiency

z Uses readily available standard inductors

APPLICATIONS

z Simple high-efficiency step-down (buck)

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.

regulator

z Positive to negative converter (Inverting

Buck-Boost)

z Isolated Fly back Converter using mini-

mum number of external parts

z Powering portable instrument, Set-Top

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

z SMPS Post-Regulator
