FEATURES  
DESCRIPTION  
The LM2670 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 output  
version.

•
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  
components. The switching clock frequency can be  
provided by an internal fixed frequency oscillator  
(260KHz) or from an externally provided clock in the  
range of 280 kHz to 400 kHz which allows the use of  
physically smaller sized components. A family of  
standard inductors for use with the LM2670 are  
available from several manufacturers to greatly  
simplify the design process. The external Sync clock  
provides direct and precise control of the output ripple  
frequency for consistent filtering or frequency  
spectrum positioning.

Wide Input Voltage Range: 8V to 40V  
External Sync Clock Capability (280kHz to  
400kHz)

APPLICATIONS  
•
Simple to Design, High Efficiency (>90%) Step-  
Down Switching Regulators  
The LM2670 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.
