Halo Microelectronics, a maker of analog and power management integrated circuits enabling energy-efficient smart systems will show its end-to-end battery fast charging solutions that include audio data switch and protection, VBUS protection, boost converter, system I/O power supply, and much more.

Recent advances in battery fast-charging in smartphones have pushed the limits of USB-based fast-charging power to 65W and more. The latest USB PD 3.1 specification enables up to 240W.

“Under such fast-charging power, high efficiencies of up to 98% or more at full power become extremely critical in delivering a practical solution. Traditional switching chargers cannot fulfill such high-efficiency requirements and switched capacitor converters have become the mainstream in such high-power fast-charging systems,” explained¬†David Nam, CEO of Halo Microelectronics. “Depending on the power level, the voltage at the USB connector could be 10V or 20V. Therefore, there is a need for both 10V input and 20V input switched capacitor converters”, he continued.

Halo Microelectronics offers both highly integrated 10V and 20V devices with the highest efficiencies of 98.3%. Furthermore, Halo Microelectronics offers a highly efficient 3A switching charger with USB power, signal line OVP, and audio/data switch devices, making Halo Microelectronics a true one-stop shop for complete battery fast-charging solutions.
