Power Integrations, in association with Weltrend Semiconductor, have announced a joint reference design describing an 18W, USB PD compliant, AC/DC power converter targeted at chargers for smart mobile devices. The design, titled DER-567, pairs the WT6630P USB Type-C PD controller from Weltrend with Power Integrations’ InnoSwitch-CP off-line CV/CC flyback switcher IC, enabling designers to produce a compact and highly energy-efficient standards-compliant power adapter.

Comments Shyam Dujari, director of marketing for Power Integrations: “USB PD adds significant intelligence to adapters and allows more power to be delivered flexibly and safely. Users can expect faster charge times for the larger batteries required to power next-generation mobile devices.”

Adds Tony Lin, executive assistant to the CEO and acting VP of marketing at Weltrend: “USB PD adoption started first in notebook PCs and is now rapidly becoming the preferred choice of smartphone OEMs for safe and rapid charging.”
