Texas Instruments  LMR14010ADDCR

The LMR14010A is a PWM DC-to-DC buck (step-down) regulator. With a wide input range from4 V to 40 V, it is suitable for a wide range of applications from industrial to automotive. Anultra-low 1-µA shutdown current prolongs battery life. Operating frequency is fixed at 0.7 MHz,allowing the use of small external components while minimizing output ripple voltage. Soft-startand compensation circuits are implemented internally, limiting the number of externalcomponents.

The LMR14010A is optimized for up to 1-A load current. It has a 0.765-V nominal feedbackvoltage.

The device has built-in protection features such as pulse-by-pulse current limit,thermal sensing and shutdown due to excessive power dissipation. The LMR14010A is available in alow profile TSOT-6L package (2.9 mm × 1.6 mm × 0.85 mm).
