+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.
