STMicroelectronics and Flextronics, the worldwide leader in smartphone and tablet power adaptors, have teamed up to develop a plug-in charging platform that achieves zero no-load power consumption.
Ideal for compact, high-power-density smartphone/tablet adaptors, the solution is built on the STCH01 controller, which reduces production costs using an innovative architecture that minimises the number of external components required.
Housed in a compact SO16N package, the STCH01 embeds a controller and two embedded power FETs in a fully integrated solution that is complemented by the proprietary no-load wakeup controller STWK01. Together these ICs allow the lowest power consumption in the market at no load with excellent dynamic load transition response. The STCH01 implements an innovative power conversion topology that maximises efficiency, reducing the size of the power transformer by 30% over industry-standard flyback solutions with low electromagnetic emissions that are further reduced using the IC’s intelligent jitter function.
The STCH01 is equipped with a full set of protections to ensure high-reliability designs of plug-in chargers.
