The LMR23615 SIMPLE SWITCHER® is aneasy-to-use 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 unregulatedsources. Peak current mode control is employed to achieve simple control-loop compensation andcycle-by-cycle current limiting. A quiescent current of 75 µA makes the device suitable forbattery-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 and also minimizes the external components needed. An extended family is available in 2.5-A(LMR23625) and 3-A (LMR23630) load-current options in pin-to-pin compatible packages, allowingsimple, 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.
