XR77103 : 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. The swi.

XR77103-A0R5 : The XR77103-A0R5 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 500kHz, the regulators can also be synchronized to an external clock in applications where EMI control is critical. XR77103-A0R5 features a supervisor circuit that mon.

XR77103-MoCA : The XR77103-MoCA PMIC is designed to power MaxLinear’s MoCA 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.
