XR77103-A0R5/-A1R0 Universal PMIC Buck Regulators

MaxLinear XR77103-A0R5/-A1R0 Universal PMIC Buck Regulators feature three synchronous 2A high-efficiency buck converters. These converters can function in 5V, 9V, and 12V powered systems with minimal required external components. Two of the outputs may be paralleled for output currents up to 5A peak with a steady state current of up to 4A. An external resistor divider can adjust the output voltage of each converter down to a voltage as low as 0.8V. These regulators can also be synchronized to an external clock in applications where EMI control is critical. The MaxLinear XR77103-A0R has a nominal switching frequency of 500kHz. The XR77103-A1R0 has a nominal switching frequency of 1MHz.
