Description for the LMR23625
The LMR23625 SIMPLE SWITCHER is an easy-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 industrial application 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 it 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 fixed-frequency FPWM mode to achieve small output-voltage ripple at light load. An extended family for HSOIC is available in 1-A (LMR23610) and 3-A (LMR23630) load current options in pin-to-pin compatible packages which allows 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.
