Cypress Semiconductor’s latest programmable SoC device includes integrated power controllers and mosfets for driving LED lighting assemblies.
“The LED lighting market is still growing despite the wider industry downturn and European markets are active particularly Germany and the Netherlands,” said Jennifer Dennis, the development manager for Cypress’ European lighting business.
The device, the PowerPSoC integrates four constant-current regulators and four 32V/1A mosfets with the SoC’s microcontroller, programmable analogue and digital blocks, and memory.
With 32V the device will support up to seven LEDs in a string on each of its four channels.
There are four low-side gate drivers with programmable drive strength which means they can also support voltages above 32V with external mosfets.
The switching frequency is 2MHz.
The device can be used in floating load buck, floating load buck-boost or boost converter topologies.
There is also 16-bit dimming for lighting applications.
