Infineon Technologies Introduces IRPS5401 Five-Output Point-Of-Load (POL) Digital Voltage Regulator for FPGAs, ASICs and Other Multi-Rail Power Systems The IRPS5401 is a fully integrated PMIC solution in a 7mm x 7mm 56 pin QFN small package that replaces multiple regulators with a single device, making it ideal for today's and tomorrow's high-density ASIC and FPGA applications Other applications include CPU multitrack systems, embedded computing systems, and communications and storage systems.
The IRPS5401 is an important part of the Avnet UltraZed Modular System (SOM), and the small package size, combined with instant monitoring and control of PMBus communications, provides the optimal power management solution required for UltraZed.
The IRPS5401 is suitable for single-rail operation from 5V to 12V, and most PMICs have only 5V. It features a 500mA LDO output and four configurable output voltage capability for the swap regulator, two of which are 2A and the other two Is 4A. The output of the IRPS5401 can be used to provide the typical rail required for core, memory, and I / O voltages. Regulators A to D have a voltage output range of 0.5V to 3.6V and LDO voltage output range of 0.25V To 5.1V.
Swap Regulator A can output up to 50A with an external power stage. Swap Regulators C and D can be combined into a low-ripple, two-phase configuration to provide 8A output. All outputs are available on most FPGAs and ASICs Requires 10W to 50W, including integrated voltage sequencing. Industry-standard PMBus commands provide an easy-to-use interface for status and telemetry. The PMBus can be used to set the output voltage, first order every 5mV.
