More Information
The LMR14030-Q1 is a 40 V, 3.5 A step down regulator with an integrated high-side MOSFET. With a wide input range from 4 V to 40 V, its suitable for various applications from industrial to automotive for power conditioning from unregulated sources. An extended family is available in 2 A and 5 A options in pin-to-pin compatible packages, including LMR14020-Q1 and LMR14050-Q1. The regulators quiescent current is 40 µA in Sleep-mode, which is suitable for battery powered systems. An ultra-low 1 µA current in shutdown 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. A precision enable input allows simplification of regulator control and system power sequencing. The device also has built-in protection features such as cycle-by-cycle current limit, thermal sensing and shutdown due to excessive power dissipation, and output overvoltage protection.
