LM2676T-3.3/NOPB Datasheet PDF - TI

●DESCRIPTION

●The LM2676 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 low ON-resistance DMOS power switch. The series consists of fixed output voltages of 3.3V, 5V and 12V and an adjustable output version.
