The SY26024 is a high-efficiency 2.2MHz synchronous step-down DC/DC regulator capable of delivering up to 4A output current. It operates over an input voltage range of 2.5V to 5.5V, and integrates very low R_{DS (ON)} main and synchronous switches to minimize conduction loss.

The SY26024 is available in a space-saving, low-profile DFN1.5mm×1.5mm-6 package.
