The LMR23630 SIMPLE SWITCHER® is aneasy-to-use 36 V, 3 A synchronous step-down regulator. With a wide input range from 4 V to 36 V, itis suitable for various industrial applications for power conditioning from unregulated sources.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 prolongbattery life. Internal loop compensation means that the user is free from the tedious task of loopcompensation design. This also minimizes the external components. The device has an option forconstant frequency FPWM mode to achieve small output-voltage ripple at light load. An extendedfamily (HSOIC) is available in 1-A (LMR23610) and 2.5-A (LMR23625) load-current options in apin-to-pin compatible package allowing simple, optimum PCB layout. A precision enable input allowssimplification of regulator control and system power sequencing. Protection features includecycle-by-cycle current limit, hiccup-mode short-circuit protection, and thermal shutdown due toexcessive power dissipation.
