  12 description: |
  13   The SY7802 is a current-regulated charge pump which can regulate two current
  14   levels for Flash and Torch modes.
  15
  16   The SY7802 is a high-current synchronous boost converter with 2-channel
  17   high side current sources. Each channel is able to deliver 900mA current.
