| 17 | Description | |
| 18 | ----------- | |
| 19 | ||
| 20 | LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter. | |
| 21 | ||
| 22 | ||
| 23 | Usage Notes | |
| 24 | ----------- | |
| 25 | ||
| 26 | This driver does not probe for PMBus devices. You will have to instantiate | |
| 27 | devices explicitly. | |
| 28 | ||
| 29 | Example: the following commands will load the driver for an LTC3815 | |
| 1f234ff1 | 30 | at address 0x20 on I2C bus #1:: |
| 8d28cd1b | 31 | |
| 1f234ff1 MCC |
32 | # modprobe ltc3815 |
| 33 | # echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device | |
