Description
-----------
LTC2974 and LTC2975 are quad digital power supply managers.
LTC2978 is an octal power supply monitor.
LTC2977 is a pin compatible replacement for LTC2978.
LTC2980 is a 16-channel Power System Manager, consisting of two LTC2977
in a single die. The chip is instantiated and reported as two separate chips
on two different I2C bus addresses.
LTC3880, LTC3882, LTC3886, and LTC3887 are dual output poly-phase step-down
DC/DC controllers.
LTC3883 is a single phase step-down DC/DC controller.
LTM2987 is a 16-channel Power System Manager with two LTC2977 plus
additional components on a single die. The chip is instantiated and reported
as two separate chips on two different I2C bus addresses.
LTM4675 is a dual 9A or single 18A μModule regulator
LTM4676 is a dual 13A or single 26A uModule regulator.
LTM4686 is a dual 10A or single 20A uModule regulator.
