Cypress's New PowerPSoC(R) Changes LED Lighting Design Landscape With Industry's First Integrated LED Driver and Controller on One Chip
SAN JOSE Calif., April 6, 2009 – Cypress Semiconductor Corp. (NYSE: CY) today introduced the PowerPSoC® family of integrated embedded power controllers, the industry’s first single-chip solution for both controlling and driving high-power LEDs. The PowerPSoC family integrates four constant-current regulators and four 32V MOSFETs with Cypress’s PSoC® programmable system-on-chip, which includes a microcontroller, programmable analog and digital blocks, and memory.
This unprecedented level of integration provides customers with a single-chip solution for high-quality LED-based lighting products, and extends into other embedded applications such as white goods and industrial control. The result is end systems with fewer components, faster design cycles, lower power consumption and higher reliability. More information on the PowerPSoC family is available at https://www.cypress.com/go/pr/PowerPSoC.
The companion software for PowerPSoC, the PSoC Designer™ development tool, enables designers to quickly and efficiently program the controllers for different lighting and power options. It also allows changes late in the design cycle without having to change the circuit board layout.
“We are bringing the unique PSoC value propositions—integration, flexibility and programmable analog—to a new set of applications and customers,” said Curtis Davis, vice president of Cypress’s PowerPSoC Division. “PowerPSoC represents an important step in the development of the PSoC platform, as well as the entire Cypress product line.”
“General illumination, medical, and architectural LED lighting applications all stand to benefit from the combination of integration and programmability offered by PowerPSoC,” stated Jeff Shepard, President of Darnell Group, Inc. “Those same applications offer long-term compound growth for the next five years of over 90 percent per year, as well as immediate growth potential in 2009.”

About Cypress’s Intelligent Lighting Solutions
LED lighting design requires a complex set of calculations with custom firmware to deliver consistent color. The two biggest problems that LED lighting engineers face are having to account for differing LED performance specifications based on manufacturing bins and the LEDs’ degradation (such as output flux, wavelength etc.) over different temperatures. With PSoC Designer, designers simply select a color from a gamut presented on-screen. Cypress offers temperature or optical feedback algorithms that are automatically applied to the selected design and programmed into a Cypress controller. This can save anywhere from weeks to months of design time for a complex design.
PSoC — Because Change Happens
PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties. PSoC devices integrate configurable analog and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings. They include up to 32 Kbytes of Flash memory, 2 Kbytes of SRAM, an 8x8 multiplier with 32-bit accumulator, power and sleep monitoring circuits, and hardware I2C communications.
A single PSoC device can integrate as many as 100 peripheral functions saving customers design time, board space and power consumption while improving system quality and reducing system cost.
The flexible PSoC resources allow designers to future-proof their products by enabling firmware-based changes during design, validation, production, and in the field. The unique PSoC flexibility shortens design cycle time and allows for late-breaking feature enhancements. All PSoC devices are also dynamically reconfigurable, enabling designers to morph internal resources on-the-fly, utilizing fewer components to perform a given task.
