10 W CV/CC charger easily meets DOE-6 and European CoC Version 5, Tier 2 efficiency standards at the end of the cable
SAN JOSE, Calif. — (BUSINESS WIRE) — April 15, 2015 — Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced RDK-420, a new reference design kit for a 10 W CV/CC USB charger based on the company’s revolutionary InnoSwitch™-CH family of highly integrated switcher ICs. InnoSwitch ICs combine the primary-side switch together with primary and secondary controllers and feedback circuits into a single, worldwide safety-rated, surface-mount package.
InnoSwitch ICs leverage accurate secondary-side regulation (SSR), using Power Integrations’ high-speed digital FluxLink™ technology to communicate direct voltage and current measurements across the safety isolation barrier. This new feedback technique permits precise control without the need for a bulky optocoupler, while avoiding the performance compromises inherent in primary-side regulation (PSR), such as limited accuracy and efficiency and poor transient response versus no-load consumption. Other benefits include: ±3% CV, ±5% CC regulation; cable voltage-drop compensation; built-in synchronous rectification driver for high efficiency; <10 mW no-load input power; and accommodation of transformer manufacturing tolerances.
Comments Shyam Dujari, director of product marketing at Power Integrations: “This reference design shows the high power density, high performance and high efficiency that can be achieved using our InnoSwitch ICs. The excellent no-load performance is one of the key reasons why several of the world’s leading mobile device makers are already in mass production of chargers using InnoSwitch ICs.”
RDK-420 can be purchased from Power Integrations. A complete reference design report ( RDR-420) is also available containing the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout and performance data required to build a 85 VAC – 264 VAC input smart mobile / USB charger with 5 V, 2 A output, measured in accordance with new US Department of Energy standards (DOE-6) and European Union Code of Conduct (CoC) Version 5, Tier 2 at the end of a USB cable.
