产品介绍

Product index

MK9218 supports wide input voltage ranges from 6V to 100V. With appropriate external high-side and low-side MOSFETs and inductor, MK9218 delivers up to 30A output current. MK9218 adopts a voltage mode control scheme to achieve excellent accurate voltage output. The switching frequency is adjustable up to 1MHz, which also can be synchronized to an external clock to eliminate beat frequencies.
