The LM2679S-12 from Texas Instruments is a high-efficiency, 5A step-down DC/DC switching regulator designed for ease of use. It features a wide input voltage range from 8V to 40V, making it suitable for various power supply applications.
This regulator offers an adjustable output voltage from 1.23V to 37V with a maximum output tolerance of ±2% over full line and load conditions. Key electrical specifications include a maximum output current of 5A, a switching frequency of 260kHz, and an efficiency of up to 92%. It also includes features such as adjustable current limit, soft-start capability, and over-current protection.
The LM2679S-12 is available in a TO-263-7 surface-mount package, facilitating integration into compact designs. The operating temperature range is -40°C to 125°C (TJ). Its design simplicity allows for the use of off-the-shelf external components, speeding up the design process.
This component is ideal for applications requiring a reliable and efficient step-down voltage conversion. Its adjustable current limit, programmable from 3A to 7A via an external resistor, provides robust protection against overloads.
