Description¶
LTC3815 is a Monolithic Synchronous DC/DC Step-Down Converter.
Usage Notes¶
This driver does not probe for PMBus devices. You will have to instantiatedevices explicitly.
Example: the following commands will load the driver for an LTC3815at address 0x20 on I2C bus #1:
# modprobe ltc3815# echo ltc3815 0x20 > /sys/bus/i2c/devices/i2c-1/new_device
