Green designs
11 November 2008
National Semiconductor has introduced six PowerWise energy-efficient subsystem reference designs.
To enable engineers to speed through the design process and deliver products that consume less power, extend battery life and generate less heat, the PowerWise reference designs combine energy-efficient devices and arrange them in a system to actively lower power consumption and reduce heat dissipation.
Each reference file kit includes an applicable design schematic, bill of materials (BOM), board layout, firmware, design documentation and FPGA source code in synthesizable Verilog or VHDL. The designs address a range of applications including portable, lighting, solar, industrial, medical, communications infrastructure, and test and measurement.
The designs cover a solar-powered lead-acid battery charger, a high-efficiency portable music player dock, a CCFL to LED conversion power supply, an ambient light adaptive LED driver, a high-performance SerDes module with easy FPGA interface and cable detect, and a load-detecting power supply.
