SNVSAH3D – DECEMBER 2015 – REVISED FEBRUARY 2018 LMR23625 SIMPLE SWITCHER® 36-V, 2.5-A Synchronous Step-Down Converter
1 Features 3 Description The LMR23625 SIMPLE SWITCHERВ® is an easy-touse 36-V, 2.5-A synchronous step-down regulator.
With a wide input range from 4 V to 36 V, the device
is suitable for various industrial application for power
conditioning from unregulated sources. Peak currentmode control is employed to achieve simple controlloop compensation and cycle-by-cycle current
limiting. A quiescent current of 75 ОјA makes it
suitable for battery-powered systems. An ultra-low 2
ОјA 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 an option for fixed-frequency FPWM
mode to achieve small output-voltage ripple at light
load. An extended family for HSOIC is available in 1A (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 …
