3 Description
The LMR16020 is a 60 V, 2 A SIMPLE SWITCHER®
step down regulator with an integrated high-side
MOSFET. With a wide input range from 4.3 V to 60
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.
The LMR16020 is available in an 8-pin HSOIC
package with exposed pad for low thermal resistance.
