GPMQ9103A is a high-efficiency, Qi-compliant wireless power receiver targeted for applications up to 15W. Using magnetic inductive charging technology, the receiver converts an AC power signal from a resonant tank to a programmable regulated 5V, 7V, 9V or 12V DC output voltage. The integrated, low RDSON synchronous rectifier and ultra-low dropout linear (LDO) regulator offer high efficiency, making the product ideally suited for battery-operated applications. GPMQ9103A is available in a 52-WLCSP package, and it rated for a 0 to 85°C ambient operating temperature range.
