LM2670 SIMPLE SWITCHER ® High Efficiency 3A Step-Down
Voltage Regulator with Sync
General Description
The LM2670 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.
The SIMPLE SWITCHER concept provides for a complete design using a ...
