LMR14020SDDAR

The LMR14020 is a 40 V, 2 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.
