3-Output PMIC for MaxLinear MoCA Solutions
Data Sheet


The XR77103-MoCA PMIC is designed to power MaxLinear’s G.hn chipsets, the MoCA 2.0 MxL370x and MoCA 2.5 MxL371x along with a single port Ethernet PHY such as the GPY241. It features 3 high efficiency synchronous buck regulators with integrated power switches and sequencing engine to provide the 0.9V, 1.8V, and 3.3V rails of the MoCA SoC. The 0.9V core rail is capable of supplying the 3A peaks demanded by the SoC(1) and is compatible with the SoC DVS control.
The XR77103-MoCA can operate from 5V, 9V, and 12V powered systems with minimal required external components, and packaged in a 4x4mm QGN that provides the smallest size solution possible. With a nominal switching frequency of 560kHz, the regulators can also be synchronized to an external clock in applications where EMI control is critical. An internal supervisor circuit monitors each converter output and asserts PGOOD once sequencing is done, outputs are reported in regulation, and the reset timer expires.

XR77103-MoCA 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.
1Worst case supply condition at 0.9V power rails around 1ms.
