portable microprocessor systems. The device contains
three step-down DC/DC converters for core, memory and
SoC rails, a buck-boost regulator for I/O at 1.8V to 5V and
three 250mA LDO regulators for low noise analog supplies. An I2C serial port is used to control enables, output
voltage levels, dynamic voltage scaling, operating modes
and status reporting. Differences between the LTC3589, …
