DescriptionThe LMR23625CDDAR SIMPLE SWITCHER? is aneasy-to-use 36-V, 2.5-A synchronous step-down regulator. With a wide input range from 4 V to 36 V,the device is suitable for various industrial application 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 it suitable for battery-poweredsystems. An ultra-low 2 μA shutdown current can further prolong battery life. Internal loopcompensation means that the user is free from the tedious task of loop compensation design. Thisalso minimizes the external components. The device has an option for fixed-frequency FPWM mode toachieve small output-voltage ripple at light load. An extended family for HSOIC is available in 1-A(LMR23610) and 3-A (LMR23630) load current options in pin-to-pin compatible packages which allowssimple, 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.
