Description
The LMR16006Y-Q1 is a PWM DC-DC buck (step-down) regulator. It is suitable for a wide range of application from industrial to automotive for power conditioning from an unregulated source. The regulator’s standby current is 28 µA in ECO mode, which is suitable for battery operating systems. An ultra-low 1 µA shutdown current can further prolong battery life. Operating frequency is fixed at 2.1 MHz allowing the use of small external components while still being able to have low output ripple voltage. Soft-start and compensation circuits are implemented internally, which allows the device to be used with minimized external components. The LMR16006Y-Q1 is optimized for up to 600 mA load currents. It has a 0.765 V typical feedback voltage. The device has built-in protection features such as pulse by pulse current limit, thermal sensing and shutdown due to excessive power dissipation. The LMR16006Y-Q1 is available in a low profile SOT-6L package (2.9 mm × 1.6 mm).
