124Description
125-----------
126
Mauro Carvalho Chehab1f234ff2019-04-17 06:46:26 -0300[diff] [blame^]127- LTC2974 and LTC2975 are quad digital power supply managers.
128- LTC2978 is an octal power supply monitor.
129- LTC2977 is a pin compatible replacement for LTC2978.
130- LTC2980 is a 16-channel Power System Manager, consisting of two LTC2977
131- in a single die. The chip is instantiated and reported as two separate chips
132- on two different I2C bus addresses.
133- LTC3880, LTC3882, LTC3886, and LTC3887 are dual output poly-phase step-down
134- DC/DC controllers.
135- LTC3883 is a single phase step-down DC/DC controller.
136- LTM2987 is a 16-channel Power System Manager with two LTC2977 plus
137- additional components on a single die. The chip is instantiated and reported
138- as two separate chips on two different I2C bus addresses.
139- LTM4675 is a dual 9A or single 18A μModule regulator
140- LTM4676 is a dual 13A or single 26A uModule regulator.
141- LTM4686 is a dual 10A or single 20A uModule regulator.

144Usage Notes
145-----------
146
147This driver does not probe for PMBus devices. You will have to instantiate
148devices explicitly.
149
150Example: the following commands will load the driver for an LTC2978 at address
Mauro Carvalho Chehab1f234ff2019-04-17 06:46:26 -0300[diff] [blame^]1510x60 on I2C bus #1::
