LMR140x0 SIMPLE SWITCHER® Step-Down Regulator

Texas Instruments LMR140x0 SIMPLE SWITCHER® Step-Down Regulators are 40V 2A (LMR14020), 3.5A (LMR14030) or 5.0A (LMR14050) step-down regulators with an integrated high-side MOSFET. With a wide input range from 4V to 40V, they are suitable for various applications from industrial to automotive for power conditioning from unregulated sources. The regulator's quiescent current is 40µA in Sleep-mode, which is suitable for battery powered systems. An ultra-low 1µA current in shut-down mode can further prolong battery life. A wide adjustable switching frequency range allows either efficiency or external component size to be optimized. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimizes the external components of the device.
