The LM2678 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 5-A loads with excellent line and load regulation characteristics.
High efficiency (>90%) is obtained through the use of a low ONresistance DMOS power switch.
The series consists of fixed output voltages of 3.3 V, 5 V, and 12 V and an adjustable output version.
