XR77103 Universal PMIC 3-Output Buck Regulators

MaxLinear XR77103 Universal PMIC 3-Output Programmable Buck Regulators feature three synchronous buck converters. Each converter is digitally programmable, requiring minimal external components. These converters operate in 5V, 9V, and 12V settings with integrated power switches. The output voltage of each converter can be adjusted by programming the values in the V_OUT setting registers through an I²C interface. The adjustable range is 0.8V to 6.0V with 50mV resolution. Output voltages can be set externally using an external resistor divider. Output sequence among the outputs, soft-start time, and the peak inductor current limit are also assessed through I²C.
