Texas Instruments  LMR23610AQDDAQ1

The LMR23610-Q1 SIMPLE SWITCHER® is aneasy to use 36 V, 1 A synchronous step down regulator. With a wide input range from 4 V to 36 V, itis suitable for various applications from industrial to automotive for power conditioning fromunregulated sources. Peak current mode control is employed to achieve simple control loopcompensation and cycle-by-cycle current limiting. A quiescent current of 75 µA makes it suitablefor battery powered systems. Internal loop compensation means that the user is free from thetedious task of loop compensation design. This also minimizes the external components. An extendedfamily is available in 1.5 A (LMR23615-Q1), 2.5 A (LMR23625-Q1) and 3 A (LMR23630-Q1) load currentoptions in pin-to-pin compatible packages which allows simple, optimum PCB layout. A precisionenable input allows simplification of regulator control and system power sequencing. Protectionfeatures include cycle-by-cycle current limit, hiccup mode short circuit protection and thermalshutdown due to excessive power dissipation.
