  • Now we are in the meat and potatoes of this device, the circuit board.

  • Surprisingly, the ONLY chip on the board is:

  • Active-Semi ACT4533B DC/DC Converter

  • This CLA was implemented with a relatively simple design using very few parts, including:

  • Several resistors, capacitors

  • Two diodes

  • Fuse

  • and one inductor
