LM2676 Datasheet (National Semiconductor) - High Efficiency 3A Step-Down Voltage Regulator

LM2676, High Efficiency 3A Step-Down Voltage Regulator

The LM2676 series of regulators are monolithic integrated circuits which provide all of the active functions for a stepdown (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 lo
