SCT63240FIAR 20W高集成度、高效率的无线功率发射器电源解决方案

DESCRIPTION The SCT63240 is a highly integrated power solution optimized for wireless power transmitter applications. This product can be combined with a specialized controller or general MCU based transmitter controller to achieve high performance, high efficient and cost effective wireless power transmitter system which compliant with WPC specification. This device integrates all the power functions in a wireless power transmitter including Full bridge power stage，5V Buck converter, 3.3V LDO and input current sensing to simplify system design and minimize external components thus improve system efficiency. The integrated Full bridge supports up to 20W power transfer and ensures efficient switching with EMI emission. The build in 5V buck convertor and 3.3V LDO provide power rails to transmitter controller and external equipment and also the power stage driver inside. The build in current detection circuits provides input current information with ±2% accuracy to support FOD(Foreign Object Detection) and current demodulation. The SCT63240 has built-in protection features including input under-voltage lockout, power stage over current protection and short-circuit protection, and thermal shutdown protection. The SCT63240 is available in an 19-pin flip chip QFN 3mm*4mm package.
