iSmartWare SW6303, The New 100W Power Bank SoC That Does It All

As high-power laptop charging becomes the norm, power banks are getting bigger and more complex. Usually, that means cramming a board full of separate controllers, protocol chips, and drivers. iSmartWare is changing the game with the SW6303, a new three-port SoC that handles everything from bidirectional buck-boost control to power management and display driving in a single QFN52 chip. Whether you are building a 100W flagship power bank or a portable storage station, this chip gives you the density and compatibility you need without the design headache.

The SW6303 is a powerhouse. It handles 2 to 6-cell series batteries, including both Li-ion and LiFePO4 chemistries. It delivers 100W of bidirectional power, supports wide input/output ranges, and provides granular 10mV voltage steps. With USB-A + USB-C + USB-C ports—featuring USB-C blind-mating—it covers virtually every major protocol, including the UFCS fusion standard, PD3.1, and QC. It even includes a 12-bit fuel gauge and direct LED/digital display control, saving you from adding extra ICs. For outdoor users, the built-in MPPT function makes solar charging effortless. With massive protection features (OVP, OCP, NTC) and port tolerance up to 30V, it is one of the safest and most efficient controllers on the market.

iSmartWare has essentially killed off the need for bulky, discrete power bank designs. By rolling five critical functions into one chip, the SW6303 helps engineers slash BOM costs, reduce thermal buildup, and save precious space. It’s the ultimate high-density core for anyone looking to build the next generation of 100W-class mobile energy products.
