MPQ4425BGJ-AEC1-P

MPQ4425B is a high-frequency, synchronous, rectified, step-down, switch-mode white LED driver with built-in power MOSFETs. It offers a compact solution to achieve a 1.5A of continuous output current with excellent load and line regulation over a wide input supply range. Synchronous mode operation ensures high efficiency, while current mode operation provides fast transient responses and eases loop stabilization. Additional features include overcurrent protection (OCP) with valley current detection and thermal shutdown (TSD). This device requires a minimal number of readily available, external components. Typically used in automotive LED lighting applications. Available in TSOT23-8 package.
