The LM2673LD-5.0 is a step-down (buck) switching regulator capable of delivering up to 3A of output current with a fixed output voltage of 5V. It features high efficiency, exceeding 90%, achieved through a low ON-resistance DMOS power switch. The device operates over a wide input voltage range of 8V to 40V and utilizes a fixed frequency internal oscillator operating at 260KHz, allowing for the use of smaller external components. This regulator includes built-in thermal shutdown protection and a resistor-programmable current limit ranging from 2A to 5A, enhancing its reliability under fault conditions. The output voltage tolerance is guaranteed to ±2%, ensuring stable performance across varying load and line conditions. The LM2673LD-5.0 is suitable for applications requiring efficient voltage regulation, such as battery chargers and system pre-regulators.
