Descripción de LMR23630
The LMR23630 SIMPLE SWITCHER is an easy-to-use 36 V, 3 A synchronous step-down regulator. With a wide input range from 4 V to 36 V, it is suitable for various industrial applications for power conditioning from unregulated sources. Peak-current-mode control is employed to achieve simple control-loop compensation and cycle-by-cycle current limiting. A quiescent current of 75 µA makes the device suitable for battery-powered systems. An ultra-low 2 µA shutdown current can further prolong battery life. Internal loop compensation means that the user is free from the tedious task of loop compensation design. This also minimizes the external components. The device has an option for constant frequency FPWM mode to achieve small output-voltage ripple at light load. An extended family (HSOIC) is available in 1-A (LMR23610) and 2.5-A (LMR23625) load-current options in a pin-to-pin compatible package allowing 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.
