XR77103-G1R2

3-Output PMIC for MaxLinear G.hn Solutions
Data Sheet

Description

The XR77103-G1R2 universal PMIC features three 2A capable1, high-efficiency synchronous buck regulators with integrated power switches. They can operate in 5V, 9V and 12V powered systems with minimal required external components, thus providing the smallest
size solution possible.

The output voltages are pre-programmed to 1.1V, 1.5V, and 3.3V. With a nominal switching frequency of 1.14MHz, the regulators can also be synchronized to an external clock in applications where EMI control is critical.

XR77103-G1R2 features a supervisor circuit that monitors each converter output. The PGOOD pin is asserted once sequencing is done, outputs are reported in regulation, and the reset timer expires. The polarity of the signal is active high.
