Power Integrations and Weltrend Semiconductor Announce 18 W USB PD Rapid-Charger Reference Design for Smart Mobile Devices
Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, in association with Weltrend Semiconductor Inc. (TWSE: 2436), the leader in USB Type-CTM Power Delivery (PD) controllers, today announced a joint reference design describing an 18 W, USB PD compliant, AC-DC power converter targeted at chargers for smart mobile devices.
Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, in association with Weltrend Semiconductor Inc. (TWSE: 2436), the leader in USB Type-CTM Power Delivery (PD) controllers, today announced a joint reference design describing an 18 W, 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.”
Weltrend’s WT6630P USB PD controller is certified by USB Implementers Forum (USB-IF) for USB Type-C and is compatible with the USB PD 2.0 baseband communication protocol. The Weltrend device reduces the BOM by combining Type-C cable detection circuits, USB PD physical layer (PHY), and components related to system-level protections such as over-voltage protection (OVP), over-current protection (OCP), and over-temperature protection (OTP).
