  1. Low Voltage Power Supply Molly, Gwyn, Sam, and Eric

  2. Fred Corrected Some Assumptions • We had assumed that components should have a rated current no more than 100-200mA above the requirement. • Fred says that components can source 2, 3, or even 4 times the required current as long as they can still operate with low current. • We had assumed that 50mV max ripple was not okay when the requirement was 35mV. • Fred says that 50mV max ripple corresponds to about 35mV typical ripple, which is fine.

  3. What We’re Working On • We want to finalize our list of proposed integrated circuits (ICs) at today’s meeting and send this list to Fred/Keith • Molly and Eric are working on HK circuit design: sensors output voltages corresponding to T and I while DC-DC converter output voltages are scaled and buffered, these analog voltages are input into several MUXs, which can be read by the ADCs in a PIC and transmitted to the GUI

  4. What We’re Working On • Sam is researching our options for ±6V converters; we will have to use multiple chips, since the part we need doesn’t seem to exist • Gwyn is looking into I2C: this is how we’re linking the GUI adjustable voltage setting to the circuit

  5. What We’ll Be Doing While We Wait for Our Parts • Schematic > PCB • Testing plan for circuit components • Program PIC, interface with GUI • I2C interface: outputting GUI-controlled voltages to circuit • GUI- make an easy-to-read table that constantly updates housekeeping values, make the voltage controls save to a file • Website stuff- make background information, team page, add schematic to work section
