XR77103-A1R0
XR77103-A1R0 is Universal PMIC 3-Output Buck Regulator manufactured by MaxLinear.
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 ponent 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. 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. A pulse skipping mode (PSM) reduces switching losses...
