LM2673 Datasheet (Texas Instruments) - 3-A Step-Down Voltage Regulator

LM2673, 3-A 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 3-A loads with excellent line and load regulation characteristics.

High efficiency (>90%) is obtained through the use of a
