The LM2679T-ADJ from Texas Instruments is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It is capable of driving loads up to 5A with excellent line and load regulation.
This regulator features a wide input voltage range of 8V to 40V and an adjustable output voltage from 1.2V to 37V. It achieves high efficiency, up to 92%, due to its low ON-resistance DMOS output switch. The device operates at a fixed frequency of 260kHz, allowing for the use of smaller external components.
The LM2679T-ADJ includes features such as soft-start capability to reduce input surge current at power on. The peak current limit is programmable via a resistor over a range of 3A to 7A. The output tolerance is ±2% over full line and load conditions.
Packaged in a TO-220-7 configuration, this component is designed for through-hole mounting. The standard package quantity is 45 units per tube.
