Head lamp – MPS MPQ4425B
The MPQ4425B is a High-Efficiency, 1.5A, 36V, 400kHz, Synchronous, Step-Down, LED Driver, AEC-Q100 Qualified.
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 over-current protection (OCP) and thermal shutdown (TSD).
