DC1558A - LTC3589EUJ Demo Board | 8-Output Regulator with Sequencing & I2C, 2.7V ≤ VIN ≤ 5.5V, Vout1-8 = 1.2V to 3.3V @ 25mA to 1.6A

Demonstration Circuit 1558A is a 2.7V to 5.5V input, multioutput power supply with a pushbutton controller and I2C, featuring the LTC3589EUJ. The LTC3589 has three synchronous buck regulators (1.6A, 1A, 1A), a buck-boost regulator (1.2A), a 25mA always-on LDO, and three 200mA LDO regulators.

The switching regulator settings such as enables, feedback voltages, operating modes and other functions can be controlled via I2C.
