MPQ4418GJ-AEC1-P

MPQ4418 is a high-efficiency, low RDS(ON) synchronous, rectified, switch-mode, step-down converter with built-in internal power MOSFETs. It can deliver up to 0.6A of continuous output current across a wide input voltage range (4V to 36V) with excellent load and line regulation. Synchronous mode offers high efficiency across the entire output current load range. Current control mode provides fast transient response and improved loop stabilization. The MPQ4418’s protection features include overcurrent protection (OCP) and thermal shutdown (TSD). The MPQ4418 is a compact solution that requires a minimal number of readily available, standard external components and is available in a small TSOT23-8 package. Typical applications include automotive, industrial control system and distributed power systems.
