Revision as of 21:11, 22 November 2007
The 2008 power supply circuit uses the same switching topology as the 2007 system with some changes, most notably a jump in system voltage to 12V from 9V to support the new motors. Another change is more analysis in the design phase including looking at possible interference with the radio and other devices that use oscillators.
Contents
Tasks
- [ ] Finalize specs on voltages, maximum current draw, and allowable frequencies
- [ ] Select a part based on the spec
- [ ] Determine how to mount batteries
- [ ] CAD the design
- [ ] Verify the design
- [ ] Fabricate
Specifications
Power Supply
- 12V operation
- Small package
- Low inductance
- High allowable RL (so we can use smaller inductors)
- Frequency does not interfere with other electronics
- Protection Circuitry (TVS:Transient Voltage Suppression)
- Matrix of Potential Power Supplies
