The Texas Instruments LM2679SD-ADJ is an active SIMPLE SWITCHER® step-down DC/DC switching regulator designed for efficient power conversion. It supports a wide input voltage range from 8V to 40V and can deliver up to 5A of output current. The output voltage is adjustable, ranging from 1.23V to 37V, with a maximum output tolerance of ±2% over full line and load conditions.
This regulator operates at a fixed frequency of 260kHz, utilizing a voltage mode control. Key features include adjustable current limit, frequency synchronization, and over-current protection. The device is housed in a 14-VSON (5x6) package, suitable for surface mount applications. It offers efficiency up to 92% and operates within a junction temperature range of -40°C to 125°C.
The LM2679SD-ADJ is designed for ease of use with off-the-shelf external components. Its adjustable current limit can be set via a resistor over a range of 3A to 7A. The integrated 120-mΩ DMOS output switch simplifies the design. This component is ideal for various power management applications requiring a reliable and adjustable step-down voltage conversion.
