IRPS5401MTRPBF

IRPS5401MTRPBF is a PMIC. It is a complete power management unit delivering up to 5 output voltages to processors, FPGA’s and other multi-rail power systems. Four high-efficiency configurable switching regulators and a source/sink linear regulator provide the typical rails required such as core voltage, memory voltage and I/O voltages. Integrated, accurate current, voltage and temperature sensing allows telemetry and fault reporting through the I2C/PMBus. The IRPS5401 switching regulator utilize fixed frequency emulated current mode control, and thus no external compensation is required. Potential applications are high-density ASIC, FPGA and CPU multi-rail systems, embedded computing systems, communications and storage systems.
