illustrate

TheLM2676 series regulators are monolithic integrated circuits that are step-down (buck) switching regulators capable of driving loads up to 3A with excellent line and load regulation characteristics. High efficiency (> 90%) is obtained by using a low-on-resistance DMOS power switch. The series includes fixed output voltages of 3.3V, 5V and 12V and adjustable output versions.

The concept of the SIMPLE SWITCHER provides a complete design with the use of a minimum number of external components. A higher fixed frequency oscillator (260KHz) allows the use of smaller size components. A standard inductor used in the LM2676 series is available from several manufacturers, greatly simplifying the design process.

The LM2676 series also features built-in thermal shutdown, current limiting, an ON/OFF control input that can adjust up and down a standby state with a low quiescent current of 50μA. The output voltage is guaranteed to be a tolerance of ± 2%. The clock frequency is controlled at tolerance ± 11%.
