With a wide input range from 4 V to 36 V, it is suitable for various applications from industrial to automotive for power conditioning from unregulated sources. Peak current mode control is employed to achieve simple control loop pensation and cycleby-cycle current limiting. A quiescent current of 75 µA makes it suitable for battery-powered systems. An ultra-low 2 µA shutdown current can further prolong battery life. Internal loop pensation means that the user is free from the tedious task of loop pensation design. This also minimizes the external ponents. An extended family is available in 2.5 A (LMR23625) and 3 A (LMR23630) loadcurrent options in pin-to-pin patible packages, which allow simple, optimum PCB layout. A precision enable input allows simplification of regulator control and system power sequencing. Protection features include cycle-by-cycle current limit, hiccup-mode short-circuit protection and thermal shutdown due to excessive power dissipation. 2 Applications - Factory and Building Automation Systems: PLC CPU, HVAC Control, Elevator Control - GSM, GPRS Modules for Fleet Management, Smart Grids, and Security - General Purpose Wide VIN Regulation VIN up to 36 V CIN CVCC Simplified Schematic VIN EN/SYNC BOOT AGND PGND CBOOT...
