FEATURES
DESCRIPTION
The LM2678 series of regulators are monolithic
23
Efficiency Up to 92%
integrated circuits which provide all of the active
Simple and Easy to Design with (Using Off-
functions for a step-down (buck) switching regulator
The-Shelf External Components)
capable of driving up to 5A loads with excellent line
120 m
Ω DMOS Output Switch
and load regulation characteristics. High efficiency
(>90%) is obtained through the use of a low ON-
3.3V, 5V and 12V Fixed Output and Adjustable
resistance DMOS power switch. The series consists
(1.2V to 37V ) Versions
of fixed output voltages of 3.3V, 5V and 12V and an
50
μA Standby Current When Switched OFF
adjustable output version.
±2% Maximum Output Tolerance Over Full
The SIMPLE SWITCHER® concept provides for a
Line and Load Conditions
complete design using a minimum number of external
Wide Input Voltage Range: 8V to 40V
components.
A
high
fixed
frequency
oscillator
(260KHz) allows the use of physically smaller sized
260 KHz Fixed Frequency Internal Oscillator
components. A family of standard inductors for use
−40 to +125°C Operating Junction Temperature
with
the
LM2678
are
available
from
several
Range
manufacturers to greatly simplify the design process.
The
LM2678
series
also
has
