title: Silergy SY7802 1800mA Boost Charge Pump LED Driver

maintainers:
  - André Apitzsch <git@apitzsch.eu>

description: |
  The SY7802 is a current-regulated charge pump which can regulate two current
  levels for Flash and Torch modes.

  The SY7802 is a high-current synchronous boost converter with 2-channel
  high side current sources. Each channel is able to deliver 900mA current.
