Description
The LMR23610ADDAR SIMPLE SWITCHER？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's 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.
The regulator's quiescent current is 75 uA makes it suitable for battery powered systems.An ultra-low 2 uA current in shutdown mode 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 of the device.An extended family is available in 2.5 A and 3 A load current options in pin to pin compatible package which allows simple，optimum PCB layout.A precision enable input allows simplification of requlator control and system power sequencing.Protection features include cycle-by-cycle current limit，hiccup mode short circuitprotection and thermal shutdown due to excessive power dissipation.

With a wide input range from 4 V to 36 V,it is suitable for various applications from industrial to automotive for power conditioning fromunregulated sources. Peak current mode control is employed to achieve simple control loopcompensation and cycle-by-cycle current limiting. A quiescent current of 75 μA makes it suitablefor 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 compensationdesign. This also minimizes the external components. An extended family is available in 2.5 A(LMR23625) and 3 A (LMR23630) load-current options in pin-to-pin compatible packages, which allowsimple, optimum PCB layout. A precision enable input allows simplification of regulator control andsystem power sequencing. Protection features include cycle-by-cycle current limit, hiccup-modeshort-circuit protection and thermal shutdown due to excessive power dissipation.
