Overview
The LMR14006YDDCT is a PWM DC/DC buck (step-down) regulator manufactured by Texas Instruments. This device is part of the SIMPLE SWITCHER® family and is designed to provide efficient power conditioning from an unregulated source. With a wide input voltage range of 4 V to 40 V, it is suitable for a variety of applications, including industrial and automotive systems. The regulator features an ultra-low standby current of 28 µA in sleep mode and 1 µA in shutdown mode, making it ideal for battery-operated systems. The LMR14006YDDCT operates at fixed switching frequencies of 1.1 MHz or 2.1 MHz, allowing for the use of small external components while maintaining low output ripple voltage.
