The following converter has been selected due to it’s high efficiency of 95%, and a relatively small footprint. Further cooling through heat sink or air flow may be required (testing required).

...

• R_Tune and C_Tune are not needed as output ripples are not significant enough for our application.

• R_Trim has been selected to be 14kΩ to provide a regulated 18.6V output.

• C_in will be 3x10uF setup to minimize input voltage ripples.

• C_out will be a 3x22uF setup (possibly a 6x10uF) to minimize output voltage ripples.

Test Procedure (In-progress)

General test procedure outlined below. Test with a substitute electrical load first, then test with the monitor. Record any problems/issues noticed.

1. Test Voltage output (regulated 19V)

   1. Voltage Ripples

   2. Test Over-Voltage protection

2. Test Input Voltage

   1. Voltage Ripples

3. Test Current Draw (1A)

   1. Ensure at least 1A current draw as specified

   2. Test Over-Current protection (draw ~10A)

4. Check for overheating under load

   1. Monitor temp while testing

   2. (Optional) Over-temperature protection
