The LTC3675 is a 4mm × 7mm IC that integrates seven regulated outputs and a dual-string LED driver.
The LTC3675 is a space-saving single-chip power solution designed for multirail applications running from a single Li-ion cell. It integrates two 500mA buck regulators, two 1A buck regulators, a 1A boost regulator, a 1A buck-boost regulator, and an always-on 25mA LDO. All regulators can be controlled via I2C.
