LM2673, LM2, SIMPLE SWITCHER 3A Step-Down Voltage Regulator
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
LM2673 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 circuitr
