MPQ4418AGJ-AEC1-P

MPQ4418A is a high-efficiency, synchronous, rectified, switch-mode, step-down converter with built-in internal power MOSFETs. It can achieve up to 0.6A of continuous output current (IOUT) across a wide input voltage (VIN) range (4V to 36V), with excellent load and line regulation. Synchronous mode offers high efficiency across the entire IOUT range. Current control mode provides fast transient response and improves loop stabilization. Full protection features include overcurrent protection (OCP) and thermal shutdown. The MPQ4418A offers a compact solution that requires a minimal number of readily available, standard, external components, and is available in a small TSOT23-8 package. Applications include automotive, industrial control systems, distributed power systems.
