The LM2679S-ADJ from Texas Instruments is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving loads up to 5A with excellent line and load regulation. This regulator features a wide input voltage range from 8V to 40V and an adjustable output voltage from 1.2V to 37V.
Key features include a high efficiency of up to 92%, a 120-mΩ DMOS output switch, and a fixed internal oscillator frequency of 260kHz. The current limit is resistor programmable, ranging from 3A to 7A, providing protection for the device and load circuitry. It also includes soft-start capability to reduce input surge current during power-on.
The LM2679S-ADJ is available in a TO-263-7 surface-mount package, making it suitable for various electronic designs. Its simple design concept requires a minimum number of external components, simplifying the design process for engineers.
This device is well-suited for applications requiring efficient step-down voltage conversion, such as efficient system preregulators for linear voltage regulators and battery chargers.
