Description for the LMR23610

The LMR23610 SIMPLE SWITCHER^® device isan 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 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.
