XR77103-A1R0 - Universal PMIC 3-Output Buck Regulator

General Description

The XR77103-A1R0 universal PMIC

Key Features

  • three 2A synchronous high-efficiency, buck regulators with integrated power switches. They can operate in 5V, 9V and 12V powered systems with minimal required external component thus providing the smallest size solution possible. Two of the outputs may be paralleled for output currents up to 5A peak with steady state current of up to 4A. The output voltage of each converter can be adjusted by external resistor divider down to voltage as low as 0.8V. With a nominal switching frequency of 1MHz, th.

XR77103-A1R0 Universal PMIC 3-Output Buck Regulator Description The XR77103-A1R0 universal PMIC features three 2A synchronous high-efficiency, buck regulators with integrated power switches. They can operate in 5V, 9V and 12V powered systems with minimal required external component thus providing the smallest size solution possible. Two of the outputs may be paralleled for output currents up to 5A peak with steady state current of up to 4A. The output voltage of each converter can be adjusted by external resistor divider down to voltage as low as 0.8V. With a nominal switching frequency of 1MHz, the regulators can also be synchronized to an external clock in applications where EMI control is critical. XR77103-A1R0 features a supervisor circuit that monitors each converter output.
