The LMR14030 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, it’s suitable for various applications from industrial to
automotive for power conditioning from unregulated sources. The regulator’s 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.
