SNVSAH2D – DECEMBER 2015 – REVISED FEBRUARY 2018 LMR23630 SIMPLE SWITCHER® 36-V, 3-A Synchronous Step-Down Converter
1 Features 3 Description The LMR23630 SIMPLE SWITCHERВ® is an easy-touse 36 V, 3 A synchronous step-down regulator. With
a wide input range from 4 V to 36 V, it is suitable for
various industrial applications 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 ОјA makes the device 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 constant frequency
FPWM mode to achieve small output-voltage ripple at
light load. An extended family (HSOIC) is available in
1-A (LMR23610) and 2.5-A (LMR23625) load-current …
