| 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. |
