   13   Richtek RTMV20 is a load switch current regulator that can supply up to 6A.
   14   It is used to drive laser diode. There're two signals for chip controls
   15   (Enable/Fail), Enable pin to turn chip on, and Fail pin as fault indication.
   16   There're still four pins for camera control, two inputs (strobe and vsync),
   17   the others for outputs (fsin1 and fsin2). Strobe input to start the current
   18   supply, vsync input from IR camera, and fsin1/fsin2 output for the optional.
