Wireless Fast Charging

CPSQ5206 is an AEC-Q100 qualified, synchronous 4-switch buck-boost controller capable of providing a regulated output voltage which is below, above or exactly equal to the input voltage. Based on different input voltage and output voltage combinations, the converter is operated in either buck, boost or buckboost mode. The converter achieves dynamic and seamless transition among different operating modes without host control.
