With PD chargers becoming smaller and more complex, the primary-side controller is the heartbeat of the system. Meraki’s MK2687 has emerged as a go-to solution, offering top-tier performance for high-density designs.
Engineered for PD fast charging, it handles USB PD PPS outputs from 3.3V to 23V effortlessly, eliminating the need for extra regulation components. Thanks to its multi-mode control—supporting DCM, QR, and CCM—and a smart multi-segment frequency curve, the MK2687 maximizes efficiency at every load level. Combined with a full suite of safety protections against overvoltage and overpower, it gives manufacturers the reliability they need while slashing design complexity.
From entry-level 18W blocks to high-performance 65W GaN powerhouses, the MK2687 is everywhere. You’ll find it in popular products from industry giants like Baseus, Bull, EcoFlow, and Momax, powering everything from portable multi-port adapters to wall-mounted 45W panels.
By packing high-voltage capability, flexible control modes, and PPS compliance into a single chip, Meraki has provided a solid foundation for the next generation of smart, compact, and efficient charging solutions.
