3 Description

The LMR23610 SIMPLE SWITCHER® device is an

easy-to-use 36-V, 1-A synchronous step down

regulator. With a wide input range from 4 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 cycleby-

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. An extended family is available

in 2.5 A (LMR23625) and 3 A (LMR23630) loadcurrent

options in pin-to-pin compatible packages,

which allow 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.
