SNVSAV8A – JUNE 2017 – REVISED FEBRUARY 2018 LMR23615 SIMPLE SWITCHER® 36-V, 1.5-A Synchronous Step-Down Converter
1 Features 3 Description The LMR23615 SIMPLE SWITCHERВ® is an easy-touse 36-V, 1.5-A synchronous step-down regulator.
With a wide input range from 4 V to 36 V, the device
is suitable for various industrial applications for power
conditioning from unregulated sources. Peak current
mode control is employed to achieve simple controlloop compensation and cycle-by-cycle current
limiting. A quiescent current of 75 ВµA makes the
device suitable for battery-powered systems. An ultralow 2-ВµA shutdown current can further prolong
battery life. Internal loop compensation means that
the user is free from the tedious task of loopcompensation design and also minimizes the external
components needed. An extended family is available
in 2.5-A (LMR23625) and 3-A (LMR23630) loadcurrent options in pin-to-pin compatible packages,
allowing 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 …
