LMR14006XDDCT

The LMR14006XDDCT is a SIMPLE SWITCHER® PWM DC-to-DC Buck/Step-down Regulator with high efficiency sleep mode. The regulator's standby current is 28µA in sleep mode, which is suitable for battery-operating systems. An ultra low 1µA current can further prolong battery life in shutdown mode. Operating frequency is fixed at 1.1MHz 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 and this allows the device to be used with minimized external components. It is optimized for up to 600mA load current which 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.
