FEATURES  
DESCRIPTION  
The LM2673 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.

Wide Input Voltage Range: 8V to 40V  
260 KHz Fixed Frequency Internal Oscillator  
Softstart Capability  
(260KHz) allows the use of physically smaller sized  
components. A family of standard inductors for use  
with the LM2673 are available from several  
manufacturers to greatly simplify the design process.  
−40 to +125°C Operating Junction Temperature  
Range  
Other features include the ability to reduce the input  
surge current at power-ON by adding a softstart  
timing capacitor to gradually turn on the regulator.  
The LM2673 series also has built in thermal  
shutdown and resistor programmable current limit of  
the power MOSFET switch to protect the device and  
load circuitry under fault conditions. The output  
voltage is ensured to a ±2% tolerance. The clock  
frequency is controlled to within a ±11% tolerance.
