The LMR16006YDDCT is a PWM DC/DC Buck (Step-down) Voltage Regulator with a wide input range of 4 to 60V, 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 28μA in ECO mode, which is suitable for battery operating systems. An ultra low 1μA shutdown current can further prolong battery life. Operating frequency is fixed at 2.1MHz (Y version) 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. Optimized for up to 600mA load currents. It has a 0.765V 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.
