3A 降压电压稳压器
DESCRIPON
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.
