PowerPSoC® Embedded Power Controller

Infineon's PowerPSoC is one of the first devices to combine the power of an embedded controller with integrated high-power peripheral functionality. This includes four internal 32 V, 1 A rated low-side N-channel MOSFETs; four 32 V, 6 MHz rated current sense amplifiers with adjustable gain settings; four 2 MHz hysteretic controllers that can be configured as buck, boost, or buck-boost; and a 32 V input voltage regulator. Due to the flexibility of working with the already integrated power of PSoC, PowerPSoC offers additional functionality including: Infineon's CapSense™ and additional digital (PWMs, timers, counters), analog (ADCs, PGAs), and communication (DMX512, DALI, SPI, RS-232) options. The ability to reconfigure power with this level of integration can simplify hardware design, lower testing time, and decrease bill-of-materials costs.

Solid state LED lighting applications are a perfect fit for the PowerPSoC family. The onboard power peripherals integrate much of a standard dimming circuit for an LED system. Infineon's PrISM™ modulation technique can reduce radiated EMI from the system, reducing visible flicker, and can utilize up to 16-bits of dimming from 100% to 0%. There are two methods to begin a design. Getting started with PowerPSoC is simple and evaluation can be done utilizing the CY3268 PowerPSoC Lighting Starter Kit. Full design activity is supported with the CY3267 PowerPSoC Lighting Evaluation Kit.
