Overview
The LMR16006 from Texas Instruments is a PWM DC/DC buck (step-down) regulator designed to convert a higher DC voltage to a lower DC voltage efficiently. This regulator operates within a wide input voltage range of 4 V to 60 V, making it suitable for various applications, including industrial, automotive, and battery-powered systems. The LMR16006 is optimized for up to 600 mA load currents and features a low standby current of 28 µA in ECO mode, which is beneficial for battery-operated devices. It also has an ultra-low shutdown current of 1 µA, further enhancing battery life.
