Tools show trade-offs in switching power supply design
A power supply design environment should provide an end-to-end online-enabled design and prototyping process.
- • Frequency switching for EMI reduction
- • Designing with high-performance FPGAs
- • Digital amps pose power supply problem
Implement OVP circuitry for safe USB charging
Using the USB as a power source for direct powering or charging a battery isn't necessarily foolproof.
- • Learn about camera phone flash units
- • Solve inter-processor comm problem in handsets

- • Stack Li-ion secondary voltage protectors
- • Using a linear regulator with 80% efficiency
- • Wall adapter for IEEE 802.3af powered device
Investing in green technologies
It was a good line, and it also happens to be true: "Moore's Law never mentioned anything about power efficiency."
Shedding light on solar energy
Solar energy harvesting is poised to go mainstream, but it's not clear which of the many technologies will take precedence.
