| 13 | Description | |
| 14 | ----------- | |
| 15 | ||
| 16 | LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter. | |
| 17 | ||
| 18 | ||
| 19 | Usage Notes | |
| 20 | ----------- | |
| 21 | ||
| 22 | This driver does not probe for PMBus devices. You will have to instantiate | |
| 23 | devices explicitly. | |
| 24 | ||
| 25 | Example: the following commands will load the driver for an LTC3815 | |
| 26 | at address 0x20 on I2C bus #1: | |
| 27 | ||
| 28 | # modprobe ltc3815 | |
| 29 | # echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device | |
