Integrated point-of-load regulator perfect for space-constrained and cost-optimised embedded designs

Mouser are offering the Infineon Technologies IRPS5401 Integrated point-of-load (IPOL) regulator. The device is a compact, fully integrated PMIC solution designed to replace multiple regulators with a single device. Ideal for high-density ASIC and FPGA applications, the device provides up to five output voltages. The device is designed for single rail operation varying from 5V to 12V. It offers one 500mA LDO output and four configurable switching regulator outputs, two at 2A, and two at 4A. The outputs of the device can be used to give the typical rails needed for memory, core, and I/O voltages. The voltage output range is within 0.25V and 5.1V for regulators A to D, and between 0.5V and 3.6V for the LDO. Switching regulator A can output up to 50A if coupled with an external power stage. Switching regulators C and D can be joined to deliver 8A in a low ripple, dual-phase configuration. All outputs are well inside the power demands of most FPGAs and ASICs covering between 10W to 50W, including integrated voltage sequencing. Industry standard PMBus commands offer an easy-to-use interface for telemetry and status, and PMBus can be used to configure the output voltages in 5mV steps. The regulator is housed in a 7mm x 7mm QFN package, perfect for space-constrained and cost-optimised embedded designs.
