As the demand for smaller, cooler, and more efficient power solutions grows, Meraki has introduced the MK91808H—an ultra-fast synchronous rectification controller tailored for high-performance flyback converters. It is a perfect fit for Active Clamp Flyback and high-frequency QR designs, supporting frequencies up to 1 MHz.
A key highlight is its self-powering capability: it eliminates the need for extra auxiliary windings, streamlining both transformer and circuit design. With a 10ns turn-off delay, 4A gate drive current, and built-in protection against shoot-through, the MK91808H ensures high efficiency and ironclad reliability. It effectively removes the boundary between consumer-grade fast chargers and industrial server PSUs.
The MK91808H has proven its worth across a wide spectrum of hardware. On the consumer side, it is the secret sauce behind multi-port solutions from brands like HEYMIX, Momax, Ruiyuan, and Yoobao, providing efficient power conversion in tight spaces. On the industrial front, it enables high-power-density designs, such as POWTECH’s 800W SiC server power supply, where its high-frequency noise immunity really shines.
By simplifying design and maximizing efficiency, the Meraki MK91808H has become a vital asset for any modern power system. As high-power-density designs become the standard, this controller stands ready to lead the charge.
