FEATURES  
DESCRIPTION  
The LM2676 series of regulators are monolithic  
integrated circuits which provide all of the active  
functions for a step-down (buck) switching regulator  
capable of driving up to 3A loads with excellent line  
and load regulation characteristics. High efficiency  
(>90%) is obtained through the use of a low ON-  
resistance DMOS power switch. The series consists  
of fixed output voltages of 3.3V, 5V and 12V and an  
adjustable output version.  
2
Efficiency Up to 94%  
Simple and Easy to Design with (Using Off-  
The-Shelf External Components)  
150 mΩ DMOS Output Switch  
3.3V, 5V and 12V Fixed Output and Adjustable  
(1.2V to 37V) Versions  
50μA Standby Current When Switched OFF  
±2% Maximum Output Tolerance Over Full  
Line and Load Conditions  
The SIMPLE SWITCHER concept provides for a  
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  
components. A family of standard inductors for use  
with the LM2676 are available from several  
manufacturers to greatly simplify the design process.  
260 KHz Fixed Frequency Internal Oscillator  
40 to +125°C Operating Junction Temperature  
Range  
The LM2676 series also has built in thermal  
shutdown, current limiting and an ON/OFF control  
input that can power down the regulator to a low  
50μA quiescent current standby condition. The output  
voltage is ensured to a ±2% tolerance. The clock  
frequency is controlled to within a ±11% tolerance.  
APPLICATIONS  
Simple to Design, High Efficiency (>90%) Step-  
Down Switching Regulators  
Efficient System Pre-Regulator for Linear  
Voltage Regulators  
Battery Chargers
