3 Description
The LV14360 is a 60-V, 3-A step-down regulator with
an integrated high-side MOSFET. With a wide input
range from 4.3 V to 60 V, the device is suitable
for various applications from industrial to automotive
for power conditioning from unregulated sources.
The quiescent current of the regulator is 300 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 LV14360 is available in an 8-pin, 4.89-mm ×
3.9-mm HSOIC package with exposed pad for low
thermal resistance.
