DescriptionThe LMR23625-Q1 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 applications from industrial to automotive for powerconditioning from unregulated sources. Peak-current-mode control is employed to achieve simplecontrol-loop compensation and cycle-by-cycle current limiting. A quiescent current of 75 μA makesit suitable for battery powered systems. Internal loop compensation means that the user is freefrom the tedious task of loop compensation design. This also minimizes the external components. Thedevice has option for fixed-frequency, forced-pulse-width-modulation (FPWM) mode to achieve smalloutput voltage ripple at light load. An extended family is available in 1-A (LMR23610-Q1), 1.5-A(LMR23615-Q1), and 3-A (LMR23630-Q1) load current options in pin-to-pin compatible packages, whichallows simple, optimum PCB layout. A precision-enable input allows simplification of regulatorcontrol and system-power sequencing. Protection features include cycle-by-cycle current limit,hiccup-mode short-circuit protection and thermal shutdown due to excessive powerdissipation.
