XR77103 - Universal PMIC 3-Output Programmable Buck Regulator

General Description

The XR77103

Key Features

  • three synchronous wide input range high efficiency buck converters. Each converter is digitally programmable requiring minimal external components thus providing the smallest size solution possible. The converters can operate in 5V, 9V, and 12V systems and have integrated power switches. The output voltage of each converter can be adjusted by programming the values in the VOUT setting registers through I2C interface. The adjustable range is 0.8 to 6V with 50mV resolution. The output voltage also.

XR77103 Universal PMIC 3-Output Programmable Buck Regulator Description The XR77103 features three synchronous wide input range high efficiency buck converters. Each converter is digitally programmable requiring minimal external components thus providing the smallest size solution possible. The converters can operate in 5V, 9V, and 12V systems and have integrated power switches. The output voltage of each converter can be adjusted by programming the values in the VOUT setting registers through I2C interface. The adjustable range is 0.8 to 6V with 50mV resolution. The output voltage also 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 set through I2C.
