AC-DC wall charger interface IC cuts smart device charge time

Power Integrations recently debuted the CHY100, an AC-DC wall charger interface IC that enables designers of mobile devices to implement the Qualcomm's Quick Charge 2.0 protocol. The Quick Charge 2.0 enables users to charge mobile devices up to 75 per cent faster than conventional technology.

The CHY100 incorporates all the necessary elements required to add Quick Charge 2.0 functionality to AC-DC wall chargers. The AC-DC wall charger interface IC detects commands from a Quick Charge 2.0 enabled device, such as a cell phone handset, and adjusts the output of the AC-DC wall charger to enable increased power delivery to the device's battery.

When plugged into a powered device without Quick Charge 2.0 capability, the CHY100 automatically disables the higher-voltage/higher-power capability to ensure safe operation. Tests confirm that smartphones with high-capacity batteries can be fully charged in as little as one hour using Quick Charge 2.0, an impressive improvement from the four-hour charging cycles characteristic of conventional fixed-voltage chargers.

The device is suitable for battery chargers for smartphones, tablets, netbooks, digital cameras and Bluetooth accessories as well as USB power output ports. Devices are available in SOIC-8 packaging.

Further information regarding the CHY100 can be found here.
