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)--
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. For more
