The LM2673T-5.0 is a step-down Voltage Regulator with adjustable current limit. It provides 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 is obtained through the use of a low on-resistance DMOS power switch. The simple switcher concept provides for a complete design using a minimum number of external components. A high fixed frequency oscillator 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. Other features include the ability to reduce the input surge current at power-ON by adding a soft-start timing capacitor to gradually turn on the regulator. It 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.
