LMR23630 3-A Synchronous Step-Down Converter

The LMR23630 SIMPLE SWITCHER® is an easy-touse 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 quiesc.
