A workshop in Portland, Oregon, saw the nine adapter designs – including several from leading power-supply manufacturers – successfully complete USB PD 3.0 compliance testing. Several of the successful designs incorporated the advanced PPS (Programmable Power Supply) option within the USB PD 3.0 standard, which enables faster charging of smartphones, tablets and notebooks without generating dangerously high levels of heat in the device itself.
The dynamically configurable InnoSwitch3-Pro integrated switcher family supports digital micro-stepping of voltage and current for precise battery charge control. These deliver up to 65 W and achieving up to 94% efficiency across line and load conditions and can be paired with a microcontroller or take inputs from a system CPU to control and monitor the off-line power supply.
The InnoSwitch3-Pro supports virtually any rapid-charging protocol, including USB PD 3.0 + PPS, Quick Charge 4/4+, AFC, VOOC, SCP, FCP and other industrial and consumer battery charger standards, as well as applications in dimmable LED ballast drivers and field-configurable industrial power supplies.
“USB PD 3.0 will be ubiquitous in mobile devices in the very near future," said Shyam Dujari, director of product marketing for Power Integrations. "The PPS option is important not only for smartphones and tablets but also now for notebook computers due to the thermal constraints of today’s super-thin form factors. With efficiency of up to 94%, our InnoSwitch3-Pro IC family enables devices to run cool, while also reducing the system BOM.”
InnoSwitch3-Pro samples are available now, priced at $1.12, in 10,000-piece quantities.
