iSmartWare is setting the industry standard for power efficiency with the SW1608. As compact, high-power density designs become the new benchmark, the SW1608 synchronous rectification controller has emerged as the go-to solution for power supply design. Now powering products from global giants like Anker, Baseus, UGREEN, and Walmart, the SW1608 is a staple in the 35W to 140W fast-charging segment. Whether it’s GaN or SiC technology, this chip is the hidden engine driving energy efficiency across chargers and power banks.
The SW1608 packs significant performance into a tiny SOT23-6 footprint. Its standout feature—VCC self-powering—removes the need for extra auxiliary windings, freeing up valuable board space for even smaller designs.
It operates up to 600kHz with support for CCM, QR, and DCM modes. Intelligent detection prevents false turn-ons, while ultra-low delay ensures precise MOSFET control. And It is the backbone of high-profile designs, including the Anker Nano 70W, high-wattage smart-display chargers, and versatile 3-in-1 power banks.
By working in harmony with primary-side GaN ICs and DC-DC converters, the SW1608 empowers manufacturers to push the limits of power density, enabling multi-port, high-wattage outputs in form factors that were previously impossible.
