Cypress Extends Lighting Portfolio with AC-DC Power Controller Family for Dimmable LED Lighting

최신 업데이트: 2013년 12월 13일

New Family Provides Cost-Effective Solution for LED Retrofit Bulbs up to 25W

SAN JOSE, Calif., 2010년 3월 29일 – Cypress Semiconductor Corp. (Nasdaq: CY) today introduced new AC-DC digital power controllers for LED lighting. The CY8CLEDAC01/02 controllers offer a cost-effective solution for both non-dimmable and dimmable LED lighting, delivering high efficiency while meeting EnergyStar requirements. They provide automatic dimmer detection, so they work with the majority of the existing installed base of wall dimmers, providing dimming down to 2% with no flicker.

The new AC-DC controllers offer primary-side sensing with tight LED current regulation, eliminating the need for opto-isolation and other secondary-side control circuitry. This technique minimizes component count to reduce board space, power consumption, and overall BOM costs compared to other isolated solutions. The new controllers also feature circuit protection not normally available with other primary-side control solutions. The built-in protection features include over-voltage protection (OVP), output short circuit protection (OSCP), peak current limit protection (PCLP), current-sense resistor short protection (CSSP), and over-temperature protection (OTP). Reference designs for both the CY8CLEDAC01 and CY8CLEDAC02, including all schematics, BOM, gerber files, and documentation to create a power supply for a fully functional LED retrofit bulb, are available at https://www.cypress.com/go/acdc.

The new AC-DC controllers expand Cypress’ lighting portfolio to effectively cover LED retrofit bulbs. They complement the PowerPSoC® family of embedded power controllers, the industry’s first single-chip solution for both controlling and driving high-power LEDs.  Together, the AC-DC family and Cypress’s PowerPSoC family cover a wide range of LED applications, from LED retrofit bulbs to high-end LED luminaires that require a variety of functions (communications, diagnostics, color-changing, etc). Cypress will demonstrate the AC-DC controllers, the PowerPSoC solution and its newly announced Powerline Communication solution at the Light Building 2010 exhibition from April 11-16 in Hall 4, Stand E15 at the Frankfurt Fair and Exhibition Center in Frankfurt, Germany.

“Cypress offers differentiated products that meet the unique needs of the growing LED lighting market,” said Curtis Davis, Vice President of Cypress’s PowerPSoC Business Unit. “The AC-DC controllers offer a strong combination of features and performance for LED retrofit bulbs.”

Availability
Both the CY8CLEDAC01 (non-dimmable) and CY8CLEDAC02 (dimmable) controllers are available today from Cypress and authorized distribution partners. They are both offered in 8-pin SOIC packages.

About Cypress’s Intelligent Lighting Solutions
LED designs offer significant new challenges for legacy lighting engineers, including efficient driving and functional dimming. Cypress offers a full range of lighting solutions, beginning with the stand-alone AC-DC Power Controllers for LED retrofits. PowerPSoC, the world’s first programmable power controller, provides the highest level of intelligent integration available, combining onboard power regulation and power drive with a microcontroller capable of 16-bit dimming to full custom color mixing. Cypress offers temperature or optical feedback algorithms that are automatically applied to the selected design, which can save anywhere from weeks to months of design time. Cypress also offers communication resources, including wireless and Powerline solutions, for customers who wish to avoid expensive rewiring.
