Texas Instruments  LMR23615QDRRTQ1

The LMR23615-Q1 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 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. 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.

An extended family is available in 2.5-A (LMR23625-Q1) and 3-A (LMR23630-Q1) load-currentoptions in pin-to-pin compatible packages allowing simple, optimum PCB layout. A precision enableinput allows simplification of regulator control and system power sequencing. Protection featuresinclude cycle-by-cycle current limit, hiccup-mode short-circuit protection, and thermal shutdowndue to excessive power dissipation.
