3 Description
The LMR23625 SIMPLE SWITCHER® is an easy to
use 36 V, 2.5 A synchronous step down regulator.
With a wide input range from 4.5 V to 36 V, it is
suitable for various applications from industrial to
automotive for power conditioning from unregulated
sources. Peak current mode control is employed to
achieve simple control loop compensation and cycle-
by-cycle current limiting. A quiescent current of 75 μA
makes it suitable for battery powered systems. An
ultra-low 2 μA shutdown current can further prolong
battery life. Internal loop compensation means that
the user is free from the tedious task of loop
compensation
design.
This
also
minimizes
the
external components. The device has option for fixed
frequency FPWM mode to achieve small output
voltage ripple at light load. An extended family is
available in 1 A (LMR23610) and 3 A (LMR23630)
load
current
options
in
pin-to-pin
compatible
packages which allows simple, optimum PCB layout.
A precision enable input allows simplification of
regulator control and system power sequencing.
Protection features include cycle-by-cycle current
limit, hiccup mode short circuit protection and thermal
shutdown due to excessive power dissipation.
